ESP?

I did the heretofore unthinkable---filled out a survey for a chance to win, oh, some great prize, cash I think. I also think my chance of winning is so infinitesimal that the odds are the same if I enter or not. The store was Price Chopper, my shopping event was brief and satisfactory (except they still don't carry the pineapple/ Canadian bacon pizza) , so when I entered the survey on the store receipt I gave very good grades on the shopping categories. At the end, the survey asked for general comments, so I referred to the question that asks if I as a customer was sincerely thanked by the cashier as I checked out. That question is impossible to answer; of course the employees are told to thank each customer, but how can the customer be a judge of how sincere the thanker is. I suggested the question be re-phrased, so the survey would ask if we were politely thanked. Why put the onus of judgment on the customer: how are we to know what lies in the heart and mind of a Price Chopper cashier?
