Strange Encounter

I was at Wal-Mart (shocker, I know!) a few days ago and had a strange encounter with a woman in the clothing department.  An attractive, middle-aged lady walked up to me and in a British accent asked if I could do her a favor.  I inquired as to what she needed and she wanted me to look inside the back of her pants, pull out her underwear, and tell her the size that was printed on the back tag.

I was in such a state of shock that I found myself doing what she asked, as if in a trance.  When I mumbled, "Size 7", she was so appreciative and exclaimed, "Thank you so much!  It is important to get the correct fit, you know!"  

Perhaps this is acceptable behavior in England....I don't know because I've never been there.  And true, it is important to get the correct fit on your underwear.  But, is it worth asking a total stranger to dig around in your pants to find your size?  I think not.
