Back when they had that plastic king sneaking into people's bedrooms and popping up, I refused to eat at Burger King because I didn't want to reward their horrible marketing.
Yes - I would've gone hungry and driven past a Burger King during that time to wait for a different option. Any different option.
Since they no longer having him peeking in windows or appearing in people's bedrooms, my conviction is not as strong as it once was and I've actually eaten there again.
