If like one man told me when the girl said something about the condoms, he said 'are those the largest you have'?
Some people are just too senditive. Or they were years ago.
About 40 years ago I had not been married very long. Wife and I were at the beach on vacation and she started her period. I walked a block or so away to a small store. Picked up a box of Kotex. There was a girl behind the counter about my age (mid 20's) she was a fun girl and mouthy. She was saying somehting out loud so other customers could hear here trying to embarras me. I don't recall how it went,but I said something back out loud that I think embarrised her.
