I'd tip at a restaurant but not at a pub. If people ask for a tip on the card machine I, being British, feel obligated to tip meaning I have to tip at weird places. For example I recently tipped at a cigarette stand in a casino in Las Vegas where all they did was sell a packet. I've even seen images on Reddit of people getting asked for tips at self service stations! Another thing I didn't talk about is annual leave. Annual leave in the US is usually rubbish compared to European countries.
