I went to this club for the first time last Saturday.

The bartender took my drink order and I tipped the regular 10%. Then either the next drink or the drink after that, she didn’t charge me. (To clarify: I mean that on one drink at this point she didn’t charge me. I just don’t remember if I had been charged for two by the time she didn’t charge me for one, or if I’d only had one prior to not being charged.)

Since she didn’t charge me and I had cash, on the next drink I got I gave her twice the drink cost since I got a free drink already and I was basically saving the tips from those two drinks. She said “thanks baby, I’m (I forget her name), what’s your name?” I told her and she shook my hand.

On the next drink that night she gave it to me for free. When I went to pay she said “you’re good.”

Last night I went again and she said my drink name and then said, “I remember you!” She gave me my drink and I tipped 10%. Then the next drink she didn’t charge me for.

It was not happy hour or anything. Is this an IOI or is she just forgetful or something and forgot to charge me multiple times?
