Justr currious. Last week I was helping a passenger who was obviously a few French Fries short of a Happy Meal, ultimately we refused him transportation. In any event, I did spend about 90 minutes with him trying to help him and get him a self place to stay for the night.
When was all said and done he offered me a $200 tip, which I turned down. I felt that would be taking advantage of someone and in any event I was just doing my job, not gratuity neede.
