Left with a bad taste

This is a nice club have had good time before however this time I left feeling irritated but saved bunch of money all because of a waitress and me being cheap I guess.

Visited the club around 2 PM and it was fairly busy. Got a seat close to the DJ booth. After a cocktail waitress, a brunette bit on the thicker side approached me. After she hands me my water I pay her with a 10$ bill and she asks me do you want change. When I said yes she hands me 3 dollars back. Bit of a shocker to me that the cost of water is 7$. When I asked her how much it is she comes back "It is 6.25, so that is seven". Anyway when I did not tip on top of that she kept hounding me till i tipped her a dollar. I guess instead of being cheap I got to get used to strip club math I guess. Since that experience left me irritated I did not get any danes not to make bad experience worse. Left after finishing my water. Definitely would be back but after a long break.
