I agree.
At least, I'm usually with a group of deaf friends who KNOW what they're doing. So, I'm proud to be with them.
There was one time when I would meet at Hooters with a few friends for WWE PPV. There was one guy there who would always claim that he already paid and accused the waitresses of cheating him. (Seriously, every single time we go there? Yeah, right. :roll
So, we ended up covering his bill. (He was at our table and we usually got all of us on the same check.)
Well, my friends and I eventually plotted a scheme. From now on, we show up earlier and order our food... and pay our bills ASAP before he shows up. Ever since then, he would com in and try that crap on us again. Yet, we've already paid for our food... so his food was on a separate check. He couldn't screw us over again.
