Bad Service The Rock Hazelwood

I went to eat at a restaurant for my daughter's birthday in March. We had a horrid experience. Initially the Manager and waitress came across as friendly. Then the waitress for some reason started behaving lika a person with bipolar. Throwing cutlery on the table like literally changed. We weren't that fussy and never gave her the run around as we are light eaters. At the end of the meal we asked for the cake which she carried like a garbage box. Anyway we finally got the bill and gave her 10% which I felt was fair given the service we got. So when she came to pick it up she looked at the bill and asked me if I didn't like her service. So I said I'm giving you what I have. She left abruptly and went all over the restaurant telling her colleagues that she wasn't happy with her tip. Well how much do people tip these days. Her service was applaing to say the least she's lucky I even tipped her for her pathetic service. I addressed this with the Manager who didn't look phased about the behaviour. I just hope the owners of this establishment know how their staff behaves.... They're too entitled and need to get customer service and eticate training. There are many competitors and a business can go from being the best to shutting down. We want to pay for good service not be bulldozed into tipping waitresses who think they've made it but giving terrible service
