Same experience as many others. I've ordered from GrubHub many times with no problems... yet the one time I had to call customer service to cancel an order because the establishment was taking too long (2 hours... no fault of GrubHub though), I had to wait on hold for 15 minutes. Ridiculous considering that you figure that everyone who has to call in is probably upset/irate about a missed order... puzzling why they don't staff more people.
