"Are you shopping for you or your wife?"
I was shopping at a local Marshall's yesterday with my wife. She had picked several obviously women's tops for herself and I picked out one for myself. I also bought a nice men's long sleeved henley shirt and a pair of joggers. My wife has mobility issues so I generally go through the checkout line alone and meet her at the door. I got to the register and a nice, attractive twenty something cashier started some very friendly, pleasant chatter as she went through the items.
Halfway through with all these women's items on the counter she asked me "Are you shopping for you or your wife?". I just said "My wife is around here somewhere." Her question caught me totally off guard but it was so non-assuming and natural that I would have been ecstatic to tell her they were for me if there weren't so many people within earshot. I'm surprised that I wished I could have truthfully said "Yes, they're for me". It was nice that it wasn't assumed that I was buying for the wife. I guess I don't look like "not-a-crossdresser".
It made my day.
