Every food delivery service I've tried has been a nightmare. They don't check the food to make sure it's correct. It gets tossed around and mangled on the way.

I had one time where there was someone else's order delivered to me; literally their name was on the bag... the delivery person grabbed the wrong bag. Then I tried to get them to fix it before he drove away and he told me to call the restaurant. Trying to get refund from the delivery service was nigh impossible. I wound up calling the restaurant and the dealt with getting me a refund and the correct food.

I no longer use food delivery at all, unless it's provided directly by the restaurant. Otherwise, I go pick it up.
