Yikes. I've "shopped" many grocery stores. I have always felt so sympathetic to the poor schmuck that had to answer "Is that the hottest pepper you carry?" and other inane questions. I will never forget the ONE truly honest answer I got: "Lady, I don't eat vegetables, I don't cook vegetables, so I don't know the answer. Just Google it."
I put in the report that the guy was quite honest, and I appreciated his honesty, rather than blathering out some blahblahblah that would have confused me if it had been a REAL question from a real customer.
I have dealt several times with employees who I felt were disabled (not physically obvious). I always just thanked them anyway, and found a different employee to answer my questions. I just didn't put the first, handicapped, employee in the report at all, except perhaps mention in the report that I noticed disabled employees, and laud the store for providing jobs for them. I believe I ran into this more in the "bag boys" than anywhere else, but do recall running into same stocking shelves and doing other work.
I believe Wendy's (yes, I know, fast food, not groceries!) prides itself on hiring disabled at front counter jobs. Kudos, Wendy's!!! (Knowing, of course, this is a case of "enlightened self interest", as they reap enormous tax benefits for same "good deed". Others are aware of the tax benefits, but still won't hire the disabled.)
