Been riding the 7 for a few years now, but this morning was a new low. Guy gets on at 74th, sits across from me, whips out a full-size nail clipper and starts going to town on his fingers. Not the 'quick trim' either—real methodical, one nail at a time, little bits pinging off the seat. No bag, no paper, no shame.

At what point are we allowed to say something? I sat there like a coward and locked eyes with a woman who looked equally horrified. Is the rule just 'pretend it isn't happening' or is there a subway grooming intervention threshold I don't know about?

I've stopped caring about most train nonsense, but nail clippers hit different. It's the noise for me. That little click-click-click cuts through headphones like it's nothing.

I asked a guy to stop once on the N and he told me to mind my business, then kept going. Wasn't worth the adrenaline dump. Now I just move to the next car and shoot a look on my way out. Not a solution, just survival.

Wait, I'm new here—how often does this actually happen? I've been taking the 7 from Jackson Heights for maybe two months and I've already seen nail clipping once, but I thought it was a fluke. Does it pick up in summer? Also, are we talking fingernails or toenails, because I need to know how much to brace myself.

My experience after a decade on the 7, E, and N: fingernails are common enough that you'll see it a few times a year. Toenails are rarer and, in my experience, more likely on late-night trips or right after a holiday shift when someone's been on their feet all day. Still gross, but there's some logic to it.

Unofficial hierarchy of subway grooming, in increasing order of offense:

• applying lotion to hands (fine, no one cares)
• full face of makeup from mirror compact (borderline, but usually harmless)
• brushing hair and leaving a tennis ball of hair on the floor (disgusting)
• clipping nails, especially if the clippings fly (legit hazard)
• anything involving feet, calluses, or nail files (leave the train)

MTA rules technically prohibit at least the nail clipping part under littering/dirtying a public space, but enforcement is nonexistent and conductors are busy. My rule: if the clippings are landing on people or seats, I'll say a neutral 'hey, can you do that at home?' once. If they're catching them in a bag, I'll just move. Confrontation ratio isn't worth it otherwise.

@astoria_arch that hierarchy is spot on. The thing that got me was he wasn't even bagging it. Just letting them fly. I don't need to be the guy who catches a MetroCard shank for suggesting basic hygiene, but if one lands in my coffee I'm going to rethink.

Also saw a guy on the 7 later eating sunflower seeds and dropping the shells under his seat. Same energy.

@westside_walt the sunflower seed guy on the D was my actual villain origin story. He had a whole plastic bag tied to his wrist and still chose the floor.

Honestly, my new rule is just check the car before I sit down. If someone's got their shoes off, a bag of pistachios, or a little manicure kit, I don't even make eye contact. Headphones in, head down.

@smalltown_steph yes, toenails happen. Usually when you least expect it. Keep a scarf or jacket you can sit on if you're stuck.

Okay that's worse. I took the 7 home last night and saw a woman doing her whole face—like dermaplaning her forehead with one of those little razors. Is that better or worse than nail clipping? It felt illegal but also weirdly impressive because the train was moving pretty jerkily.

Thanks for the warnings. I'm going to start checking seats before I commit.

@smalltown_steph I'd put dermaplaning above makeup but below nail clipping, mainly because the shavings are smaller and less likely to end up in someone's coffee. Still, any blade near eyes on a moving train is a safety problem. The real tell is how much mess the person is leaving behind. If someone is catching their own debris, I file it under 'weird but contained' and leave them alone.

One thing I've learned: don't sit at the very end of the car if you want fewer grooming performances. The slightly less crowded middle cars don't just have more witnesses—they also seem to have fewer people convinced they've found a private dressing room.

If you ever do want to tell the conductor, the MTA has a Go/See/Say thing through the app, but in practice that's better for bigger issues. For a quiet nail clip in a ziplock-free zone, changing seats is usually the cleanest exit.

@astoria_arch 'weird but contained' should be the official slogan for the 7 local.

@westside_walt new rule for the thread: no visible human shell removal. If it comes off your body and isn't a jacket, it stays home.

Also, I once watched a man use the little pole armrest as a pumice stone for his heel. I did not say anything. I simply floated out of my body and got off at Queensboro Plaza a shell.
