Top annoying commuting accessories

In no particular order:

-- headphones that don't work. I hate when I can hear the music of the
guy on the other side of the car.

-- bikes. Especially during rush hour and people can't even fit into
the car, much less a bike.

-- women with lots of large bags and every time they turn around they
knock people around.

-- women in ridiculous heels that every time the train sways slightly
they topple over

-- people on the train who have really stinky shoes/feet and insist on
putting them on the seat.

-- push-to-talk phones. I don't want to hear you or the jarbled
response of whoever you're trying to talk to

-- phones that double as a radio tuner. Get headphones.

-- little kids. Ok only sometimes. But screaming babies are annoying
when I'm trying to do work or sleep
