A further 32 per cent of those polled said people should leave a 10-15 per cent tip, and just 1 per cent claimed a tip of over 20 per cent would be appropriate.
Nearly a fifth of restaurateurs (18 per cent) said tips should be at the customer’s discretion, and not something they are expected to pay.
The poll also revealed that customers do not usually leave a further cash tip if a service charge is added to the bill.
“The subject of tipping is perhaps one of the most hotly-debated subjects both around the restaurant table, and amongst industry professionals,” said Mike Conyers, chief executive at ResDairy.
“To find out what the restaurant and food-led pub owners and staff are thinking, whilst you check your bill and calculate the tip you’ll leave, we thought it would be interesting to run this poll to gauge opinion.
“The results were interesting, not least the fact that unlike our friends in The States, tipping in the UK is still very much viewed as an ‘option’ this side of the pond – stark contrast to attitudes of those operating business in the US.”
