To the two waitresses on the patio last night, two glasses of wine was 12.25 and you kept the seventy five cents each time you gave me my change. At ten percent, I would have gladly tipped you 1.25 each time, however I found it quite rude for you to just help yourself to my money so your 'tip' became the change you helped yourself to. I don't know if this is a new industry practice or just something you do at your establishment, but it's bad manners and bad business!
