We got harressed for not leaving a tip- On that occasion I would have gone to jail before I would have given a cent!!!
A waiter gave my 7 yrs old girl a coke, she had ordered a diet/light coke. When we called the waiter back and said we thought that it wasn't diet, he said it def was and that he had poured it himself. I then tried it and like my girl I was sure it wasn't diet coke, so we reasked the waiter and this time he got quite narky and said its diet, are you calling me a liar. My girl (now starting to get upset) still wouldn't drink it, so we just ordered another one, that one was fine. After a further 10 mins the waiter saw my girl do a blood test as she is a diabetic, at that piont he ran over and grabbed her drink, admitting that half way through pouring it the machine had stopped so he just filled it with full sugar coke . I was very angry and spoke with the manager. You can imagine my surprise when the same manager questioned our non tip. My husband replied- heres a tip employ honest and pleasent staff if you expect customers to return, and if you do not want to end up getting sued, then we just walk away- non police called thankfully
