Forget GrubHub. I used it to order pickup from a restaurant I'd never been to so that I could see the menu. I waited 12 minutes and then went to the shop, and the guy hadn't made the order because he was waiting for the GH driver to be assigned.
Next time I'm writing down my order and calling. No coercive UI, and no middleman charging overhead.
A cool and chill place for cool and chill people.
