TITLE: Can I legally refuse to pay for terrible food?
POST: I live in the province of Ontario, Canada.

Today I had some disgusting food (It was Nachos, how do you screw that up?) and I accidentally left without paying a few hours later (honest mistake).

I was on my way back to the pub when I realized that I probably should have refused to pay for the crap food they gave me anyway, so I turned around and went home.

Normally I would just pay for the crappy food and not order it again, but with having to drive back there and also combined with an un-related incident where the owner of the place was being a huge pain in the ass to a bunch of us - I decided to turn around and go home.

I'm expecting them to bring it up next time I walk in there (they have beach volleyball courts and I've played there in a league twice per week for 9 years straight).
TL;DR: 
Do I have any right to refuse to pay for crap food in Ontario and does the owner of the place have the right to refuse me future service based on this incident?
