I had a first last night.
We stopped by a restaurant last night after soccer practice, and there was a 50th birthday party going on (roughly 15-20 people). They were having a good time laughing and drinking, but two ladies had this obnoxiously loud high pitched laugh and, apparently, everything was the funniest thing ever. I was a good 20 feet from these ladies, but could not converse with my wife and daughter next to me because it was so loud and consistent.
About 10 minutes in, it became apparently that this shrill cackling was going to continue as long as we were there. I exchanged looks with a few other patrons as well as the exasperated wait staff and came to the conclusion that this had been going on before we arrived. When the server brought our food out, I asked them to box it up because we weren't going to stay.
I left him a nice tip and a note wishing him a quiet evening.
I about said something to the ladies, but decided not to interfere with their fun (they weren't swearing or doing anything inappropriate). Anyone have something like this happen to them before? I'm curious how you handled it/would have handled it.
