Grubhub drivers are the WORST consistently of all the delivery services. It is very rare that they follow my contact rules. I simply want them to knock on my door so I know my food has arrived, and maybe 1 out of 10 deliveries am I notified. Additionally I've watched several drivers drive around in circles or get lost bringing my food. If you don't know how to follow a GPS find another job! I'm done ordering through Grubhub.
