AITA for not tipping at the brewery after they got my order wrong and charged me for the wrong item

I was at a brewery and I ordered a pitcher for my table. The bartender pours a single glass of the beer and brings it to me. I tell them I ordered a pitcher not a glass, and they ask me if I still want it. I say sure, but reiterate that I need a pitcher. I assumed incorrectly that they were gifting me the glass the bartender poured by mistake, I only realize this when I get the tab. Rather than argue about the situation I just didn't leave a tip because the price of the beer they charged me for was more than I had planned on tipping.

I told this story to some family members and one said I should have left a tip and that it was obvious they were charging me for the mistake because I said I would take it.
