Tipping in general annoys me when it is expected for normal service. If someone like an uber driver does a great job and tells me about the city or something then I like to be able to tip to show my appreciation. But I don't like any sort of industries where a 20% tip is always expected. Why should I tip a bartender for handing me a beer? Just raise the prices.
