i saw some tourists (family of like 10) on the 2 train and they kept looking at each stop and talking to themselves as if they were trying to figure where to go. eventually i took off my headphones and was like.."ummm, do you guys need help with directions". turns out they were wanting to uptown to times square and they were going in the wrong direction. luckily, the next stop was atlantic ave and they could switch trains there without paying again. they were worried that they had to get out and pay again to back in the correct direction.
