It was a very hot summer in England last year and at one secondary school the dress code was no shorts allowed so a few of the boys turned up at school wearing skirts. It made the front page of the tabloids but I can't remember what the eventual outcome was.

rules are rules. its strange you can walk in with shirt and shoes with your cock hanging out though. what about socks?

Yes, shoes and shirt required. Beyond that, they should not because more restrictive dress codes than that have often been used to discriminate against minority groups or other cultural groups, ie. hippies, that they owner doesn't like. The business has the legal right to go ahead and do this, but when they do, they deserve the protests, boycotts and other forms of condemnation that it will invite.

Definitely, no one wants to have to look at moobs while eating.

Of course they should be able to have a dress code.

Clothing is something that can be controlled, unlike race or sex, so yeah,.places of business have every right to set standards as long as they are applied consistently and equitably...shoes might be a safety requirement when glass and other sharp objects might be around...

We have restaurants here that don't allow men or women to wear hats inside or even sleeveless tanks...don't like it, don't go.

Yes, it’s their property and they should be able to set whatever policies they want, even stupid policies. If you don’t like their policies, don’t go there.

Forget the coat and tie. That one would not get much business today. Are shoes and shirt required? Some people do not like eating in front of shirtless men and this should be taken into consideration. The last thing is "who's restaurant is it?" The answer to that shows who can set the attire policy.

Yes

Within reason. Many years ago in my hippy days a few friends and I were asked to leave a bar because we were not wearing ties. Of course it was because we had long hair which seemed to upset the landlord as there were other casually dressed guys in the bar not wearing ties. We pointed this out and the landlord then invited us outside to sort this out . We were four very fit guys in our twenties and he was one flabby middle aged guy. Was he brave,stupid, or had he just been imbibing too much of his stock. I can't remember how it ended but I think we took pity on the guy and left his bar.

In high school I had a friend whose parents owned property in a high-end neighborhood. He and a couple of friends tried to go into the clubhouse for lunch but were refused entrance because it required a black tie (they were in swim shorts). So, he went back to his car and pulled out black ties for everyone. The clubhouse had to let them in since they were technically in compliance.

To answer your question, I believe, like @Marine, that it is reasonable for a restaurant to set reasonable clothing requirements. Also, if I remember correctly, being barefoot is usually considered a health violation.

I believe it is reasonable for a restaurant to set clothing requirements as I would not like someone to be walking around barefoot or without a shirt sitting at a booth.
