...for wearing shorts.
He tried to walk into the restaurant on Gala Night with shorts, but the Maitre'D refused him entry. He argued with the Maitre'D for a bit, but was not allowed inside.
Somehow, he managed to sneak inside wearing the shorts. The Maitre'D found him seated at a table near us and escorted him out of the restaurant.
I'm not a particularly stuffy or formal person, but I actually appreciated that on Gala Night.
