Do you know proper subway etiquette?

With 6 million daily subway riders in a system seeing more breakdowns and delays, being considerate of our fellow New Yorkers may be all we've got. Yet when it comes to subway etiquette, we all do see our share of subway faux pas.

The most-cited offense is busting onto a train before exiting passengers have gotten off. We thought manspreading would come in as the No. 2 peeve but that went to people who don't take off their backpacks on a crowded train, riders told Fox 5.

Now to be clear, most New Yorkers are thoughtful. We just tend to notice the few amongst us who might've missed etiquette class, for example, to learn how to avoid conflict on the subway stairs.

While most New Yorkers agree on subway etiquette, one issue caused confusion. Who gets to go through the turnstile first: the person leaving the station or the person entering?

For an expert opinion, we went to etiquette guru Thomas Farley, a.k.a. Mr. Manners.

"This is a little confusing and it's because almost 99.9 percent of the time if you're leaving a store, you should come out before the new people come in," he said. "This makes more space for everybody."

But when it comes to our dilemma at the turnstile, the train decides who goes first. If the incoming subway rider has a shot at catching the train, Mr. Manners said you should let them.

"The outgoing passengers should step aside," Farley said. "Let those running passengers get on because for [the former] it's a second difference but for the people trying to make the train, it could be a 10-minute difference.

And given how much can get done in a New York minute, gifting a fellow New Yorker 10 minutes is a courtesy.
