I'm probably going to either disappoint or surprise you. There is no perfect delivery service, for one simple reason, they all profess the principle of who is the fastest. And that's what the customer pushes them to do. My friends have an acquaintance who works in the delivery of Grubhub, he explained that most orders are formed with the wheels, not in advance. And you know yourself, at a brisk pace, especially in the evening, when there are a lot of orders without omissions is not possible. Try the resource to read grubhub reviews and understand all the specifics of shipping. Good luck to you!
