When I eat out, I never, ever leave a tip by credit card - that just sounds a bit remote to me and I'm not confident that it will actually reach the people it's supposed to.
It seems that greedy and unscrupulous owners have developed an imaginative range of ways to keep some of the cash I leave instead.
Thanks to Kezia Dugdale for raising awareness of Unite's Fair Tips campaign which aims to ensure that more of the tip money is actually given to the staff and not pocketed by the owners.
This is just part of Kezia's crusade to quiz coffee shops in Edinburgh about a variety of things, including their recycling policy. I shall look forward to seeing the results.
