Is this a thing now? I don't get out much so maybe I'm out of step but 3 times in the last month I've been given the bill including service charge and then been asked for a tip too. Today it was an online payment, 12.5% service plus a tip option for the waiter of either 3, 5 or 10%. No option to not give a tip. At the weekend it was 14.5% service plus tip requested! Surely, the service charge is the tip? AIBU to not add the tip? I did as I hate for waiting staff to miss out but think they should get the service charge...
