I have hired a bartender for our wedding. She has been extremely difficult to work with and the only vendor I have had any issues with....waiting 2 weeks to get back to me, telling me to look at the contract rather than giving me a direct answer, forgetting that she promised us free ice & a cooler. I'm honestly worried she's going to forget items.
BUT I refuse to tip poorly but what is a normal amount for tipping a bartender for 7 hours? The total cost is 830, including a bar, cooler, and drinks for mixing. What do you all think an average tip would be?
Thank you!
