How do you feel about restaurants with messy floors?

I had dinner tonight at the Texas Road House, which is a steak place. Customers are given a bucket of peanuts when served, and are expected to throw the shells on the floor.
I am uncomfortable with this, even though it is intentionally done.
There is a pizza place in town (Skippolini’s) which has the floor of the restaurant covered with sawdust. I am also uncomfortable with this.
Do you know of other restaurants that do this?
How do you feel eating in a messy place, even when it is intentional?
