Would you say anything?

We went out to eat over the weekend and were early for our reservations so we sat at the bar and ordered some drinks

I had 2 sips of my drink and when I went back for a third I knocked the glass over

We wiped it up I apologized to the bartender and went back to drinking my glass of water

The bartender said "Let me get you another drink"

I said no that's alright, I'll stick with water

She said "It's no problem, I'll take care of it"

She brings me another drink, I drink it, our table is ready and when the bar bill comes both my drinks are on the bill

Uh, what??? I thought she was replacing a spilled drink not giving me a second drink

I wanted to say something, my girlfriend wouldn't let me

It definitely wasn't the money, but that's odd right?
