Is it right that a supermarket should be able to dictate the way we dress?

I can't believe I'm reading some of these answers. If these greedy fat cat corporations didn't cause so many small shops to have to close down then people would be able to shop in there own towns and villages, where local people know each other and have a lot more tolerance for each other. Who cares if somebody is in their pj's. And why does it necessarily have to be an unemployed chav you bunch of stuck up snobs.....By the way I have a job and an education, but I don't look down my nose on lesser educated or people worse off than me. Get your heads out of your bums.
