Good post, but I have a question. What do you do if a tablemate slides under the table?
You see, we were dining at a table of 8 and 1 couple was a man and a gorgeous woman. Right after we sat down and the drinks were ordered I saw the man sliding down his chair and then under the table. The woman was unconcerned and didn't appear disturbed at all. After a few moments I told her "Maam, I think your husband just slid down his chair and under the table." She replied, "No he didn't, he just walked in the door!"
