Commissioned by online marketplace OnBuy.com, the survey also revealed that over 20% of British diners would still tip at a restaurant even if the service was poor.
32% of restaurant-goers would feel too embarrassed to ask for the service charge to be removed from a bill, despite bad service.
When asked why they tip, the majority of those surveyed answered that they do so because “that is just how things are done”. A further 24% said they only tip because they feel a “social pressure” to do so, and would feel ashamed not to.
15% of participants stated that they tip because they do not feel that workers “earned enough”.
It was recently revealed that over half of British diners are unsure whether to leave a tip in restaurants in case it is not passed on to waiting staff.
A survey of 19,317 people revealed that the majority found the tipping process 'confusing' and were unclear how the money was shared out.
A third of diners were unsure how much of a tip they should leave, while three quarters of over-55’s struggled to use a card machine to leave tips.
Last year a Government consultation proposed forcing restaurants to be more transparent over tipping practices, but there has been no further update on the plans.
