In one of my first trips to the UK back in the 90s, I had an afternoon to kill and decided to visit the legendary "Harrods" department store in central London.
As I was strolling through this amazing store, I was so busy gawking I literally walked up on and through a tiny nun. Down she went, it would have been a 15 yd penalty for a block in the back. I immediately bent down to help her up, repeating "I'm so sorry, Sister." As I reached to her, her head turned to me and I realized.....she wasn't a nun. It was an elderly Muslim woman in a black burka, and she was chattering away a mile a minute (in what I assumed was Arabic) as she was helped to her feet. She was not happy.
Within a minute of me running in to her, store security (two large men of Middle Eastern heritage) arrived on the scene. One of them talked to me in English, the other to the woman in her language. I contritely explained exactly what happened, and apologized. No idea what she told the other guy, but at my first opportunity I beat feet and left the store. I kept imagining the BBC headline, "DoD Official Assaults Elderly Muslim Woman in Harrods."
