When we visited Cheltenham from the states, the weather was very warm. Our children were wearing shorts and were quite happy. When we went to Bowood, there were children running around on the playground in their underwear which it seems is a very European thing to do. I don't have any pictures of this.
Back home in Canada we tend to tip for most things. However, it seems in the UK you don't tip at bars and clubs. A local at a pub proceeded to tell me how he could buy a beer with my 2 pound tip I left the waitress and that I appeared as snobbish leaving a tip. It was really retarded but I got the point.
People here tend to not tip at all. So save your cash for your next pint.
