I'm with you on that one too. That is the most uncomfortable thing to have to do as a guy. I agree that cashiers can be pretty rude sometimes. All it takes is that "look".
Another story I have. I was at Haircuttery last weekend and the girl scouts were out front of the place selling cookies. Well, my sister in law got 2 boxs and I was the one to hold them in the salon. Well, I'm sitting there after my haircut and this girl comes in with this guy and stares me down with this "look". I'm thinking. What is that all about *L* Because I am buff. Of course she could have been thinking, "gee, what a thoughtful guy for buying those girl scout cookies". *L* O well. I was feeling sharp after I left that place
