There's a type in the system that is probably not on this forum... the pig lady.
She's the one standing on the escalator that doesn't let anyone by (escalefter)
She's the one that waddles through narrow spaces, winds into oncoming traffic, and checks the contents of one of her four bags in the middle of the path.
She's the one that will cut to the front of the platform and charge into a car before anyone can get out, or blocks access from the door to get out.
She needs a few seats for her bags. Only about 1 in 10 are this lady, but they really hold things up.
This is how you handle those cases:
