Of course but there are still general trends, such as the one I stated about the UK and France. For example, in London and Paris people probably don't shop like I said, but generally they do. I expected Americans, being primarily car oriented and shops being spread far apart, would stick to giant hypermarkets. That said, I have learnt that making any kind of generalisation about America is sure to bring a response that America is actually infinitely varied, so I completely retract any comment I ever made about the US
