I will echo what everyone else is saying about getting off the lift with skiers. I always try to get on the outside edge of the lift for this very reason if there are skiers with me, just one less person to deal with.
My wife is actually the worst. I can't tell you how many times she's inadvertently tripped me up with one of her ski poles as she just pushes off and calmly skis away. Sometimes I wonder just how "accidental" it really is though, lol.
