WWtOTdo or was I in the wrong?

I was in NYC last week, and I wanted an authentic NYC deli sandwich. I go into Hell's Kitchen to a deli, order me and my daughter sandwiches and leave because they didn't have any place to sit and eat.
On the way back to the room, we come to a bar and grill that has tables set up outside, 90% of them were empty. It was 2pm and it was half empty inside as well.
So we grab a two top, order a beer and a Coke. While the waiter was getting our drinks, we break out our sandwiches and start eating. The waiter comes back with the drinks and goes crazy. "You cannot sit at my table and eat food from somewhere else, we have food here!"
I tell him, oh well, down my beer and leave him $5 for the beer and didn't pay for the Coke. I told him I wasn't paying for the Coke because you won't let her sit here and drink it.

Now, if the place was packed, and there was only one table left, I wouldn't have sat, but they cut off their nose to spite their face.
We would have sat there, had a couple beers, cokes, maybe an appetizer, and dessert, instead my money went somewhere else.
