Steven's Pass, Washington, has a chair that goes up, over, and down the other side of a ridge, serving both sides of the ridge. All riders from either direction must get off at the top.
My wife, her cousin, and myself were riding up. We were getting ready to unload when cousin Debbie said that a fold of her pants was caught under the seat of the chair (the seat could be flipped up so it didn't hold snow overnight). We were right at the get-off, I got off, Debbie could have stood up, released her pants, and skied away. Debbie and my wife stayed on the chair and rode down the other side of the lift. I'm on the snow quietly saying, "I don't know those women." The lift had to be stopped at the bottom on the other side, they walked around the bullwheel, got back on, and finally got off at the top.
They were mad at me! I was very brave and refrained from laughing too loudly, and they expected me to be sympathetic!
The best thing to do if one can not get off the chair is to be sure your legs trip the shutdown switch. Do not jump off if you're suspended in the air after you miss the real get-off ramp. Do tell the lifty that you're stuck.
