Loud Obnoxious People in Restaurants

We were dining at a large upscale Italian chain in a city not known for it's culinary treats. The place is in an area filled with professional and medical buildings so the clientele was well dressed and sedate. Even though the place was packed there was one table of 6 women, I doubt that they were Republicans, who were shouting and laughing so loudly you could hear them above all the other diners from across the restaurant.

I asked the waiter if we could be reseated since we were close, but he said there were no empty tables and there was a line in the foyer of people waiting to get in. He said other people had complained but it was company policy not to do anything but serve them quickly and hope they leave,"we have learned that if you ask them to hold it down that just makes them louder".

It's funny, I've seen restaurants ask people with crying babies and children to leave, but the grownups we are stuck with.
