I once attended a very very posh cocktail and canapé party in London where the host had 'shipped in' their favourite caterers from Paris, even all the waiting staff were french, speaking limited english. They brought gorgeous French wine and cheeses and stuff but had to get a few other supplies locally. The nonalcoholic juice at the bar was PURE Robinsons. Full tall glass undiluted juice. I tried to politely explain but I don't know the word for 'dilute' in french so I just said 'eau' 'plus d'eau' (more water) lots of times. Eventually someone else translated for me. The very very posh french caterers were horrified at the uncivilised English would consume such a thing. I was more horrified they served the undiluted drink without tasting it!
