I agree that Are you being served is my fave British sitcom - I love Mrs Slocombe's pussy talk - however British better than American? Considering all British comedies like this are all childish innuendo humor, it is not better than the American sophisticated humour. That isn't to say that there aren't hundreds of crappy American sitcoms but the ones that hit the mark are really really great.
I loved this show & sometimes watch reruns when they're on. It's an old fashioned type of humour that you don't see so much on current sitcoms. Each character had their part to play to make it a great comedy. Everyone knows who you're imitating when you say "I'm free" or when you're referring to Mrs Slocombe's pussy. A real classic show.
