Too greedy to turn down orders when at capacity

Mr D Food. I definitely will never be ordering from you guys ever again, uber eats it is. I waited and waited for my order, called 3 times to be told that the driver is on the way. Eventually I call back and I'm told that the order has been taken by someone else. *** does that mean?? And it's too late to reorder from the same restaurant. The problem is guys are greedy and won't admit when at capacity, you accept orders when you can't handle them
