Tipping is done in Britain just as in the United States, but at a lower level than you would back home, generally 12.5% to 15%. Tipping more can look like you're showing off. Don’t tip bar staff in pubs—although you can always offer to buy them a drink. There's no need to tip at clubs (it's acceptable at posher establishments, though) unless you're being served at your table. Rounding up to the nearest pound or 50p is appreciated.
