Late to the party but I'll play anyway. $45? for two? Unrealistic expectations, you haz them. I like sushi a lot and can easily eat $45 myself BEFORE sake and I like expensive sake so my sushi bill is usually about $100 before adding another party. I went to sushi with a buddy of mine and we were catching up and eating and drinking and the bill came and it was $220! We both looked, laughed and threw our $ down. I may have met my match, lol.
Dubbs, you got punked a little. The bigger question is did you have a good time? Next time you'll be better prepared. Standing up for yourself isn't being a dick. Politely calling someone out who overstepped isn't rude, it's manly. You'll gain people's respect for that. If they don't respect you for that, fuck 'em, they were trying to take advantage.
If this doesn't make sense, let's go get some sushi and figure it out. We'll split the check, right?
