Against those that don't want to follow the owner's rules for eating there.
This is just an expanded version of the , "No Shirt-No Shoes-No Service" rule many places have.
Nobody wants to be enjoying a meal with their family with low-lifes walking in with their pants down around their knees and their underwear showing.
Not appetizing at all.
This Washington couple need to take their "offense" somewhere else if they don't approve of the owner's rules.
A Polish buffet, (owned and operated by people from Poland) opened up in our town, years ago. We tried it once. But there was a sign on the buffet that said, “eat as much as you like, but you will be charged extra, if you leave entrees on your plate, and don’t eat them.” The food was pretty good, but there were a lot of authentic Polish dishes, that people wanted to try, but didn’t care for. They went out of business in less than a year, and I don’t think it was because the food wasn’t good.
