Unfortunately, just a few weeks ago in London, someone at my table lit up WHILE I was eating. I can't tell you the self-control it took not to introduce my previous meal to her..... Of course, I said nothing, but as a non-smoker, it was absolutely horrible.

I had to laugh about the dental hygiene remark. I've been told that my light teeth are what tipped me off as an American!

Analise, thank you (and many others, as well!) for your excellent comments.
