Yes. I'm aware of the signs you're talking about. They, combined with the general attitude in your second sentence, have contributed to the common misconception that being barefoot is against the law or some health code. Many of those signs you see will even say, "Shirt and Shoe required" - by the Health Department. It's a lie.

Regardless -- barefooters should carry some sort of footwear if going to any place they've not gone before, just in case.
