Don G has pretty much nailed it but add one more, the drunk. They typically do all that Don mentioned and more. Like others we ask for a very large table figuring that the odds are better should we get a table with at least two other couples of meeting and hitting it off with really nice folks. The other thing that nobody has mentioned is the location of the table. I detest those booths. With my knees and feet the way they are it is exceptionally difficult to get in and out of the booth and quite frankly I am glad it give me a good excuse to tell the Maitre D' that I must have another table. I just don't like sitting in them.
