Cool idea, seems like the next level up from conveyor belt sushi. I like the idea of putting food on my card at the time it's ordered so that there's no complicated bill paying process at the end of the meal.

Actually the card that you use isn't your final payment card but a temporary tally card for the restaurant. You still have to go through a checkout process later before you leave to make the final payment.

Yeah that's way less cool.

Finally, a way to avoid tipping without making my date think I'm an asshole.

ha... ya my thoughts exactly
