I was on the 4 bus in Denver last Tuesday heading home from work around 6pm. This older guy hops on and sits next to me and starts telling me he forgot his wallet and needs $2.75 to get to Aurora. I told him I didn't have cash and he reached into his mouth and pulled out his top dentures and held them out to me. He said 'these are worth at least $50 you can sell em.' I just sat there frozen while he tried to negotiate the price down to $1.50. The driver kicked him off at the next stop but I still think about those teeth every time I ride that route. Has anyone else been offered something weird as payment on a bus?
