The thing is it's feel like we don't belong here; everyone was prim and proper and we were just loud laughing with the slightest joke someone cracks!

As a person who works in the restaurant industry I do thing everyone belongs in any restaurant regardless how they dress, look or act. As long as you pay for the food and service you are good. Those places who have sort of "standard" or "dress code" really turns me off and its a problem in our society. Have fun, you deserve and need it! The world is too serious already.
