Once while shopping a large department store chain, I came across a clearance table of active wear, leotards and tights (my weakness). While rummaging through the selection, an elderly SA approached and discretely told me these were for women. I politely responded" Oh yes, I know, Thank you ", and continued to shuffle through the packages. She put her hand on the same package I was about to pick up and said, "But sir, these are not for men, there for women". I gently responded again, "Yes, thank you". She took a step back with a look of confusion and shook her head while muttering to herself, "but I don't understand" and walked away. I'm sure it was her first time encountering one of us.
