Sonic Drive-In review: the long wait for my drinks

I ordered 3 drinks and paid with my bank card. I sat there waiting, waiting, and waiting to receive my drinks. I notice that during my wait the drive thru serves a car (which ordered shortly before me) some food, and another car next to me receives food 5 minutes after I order. I did not see any other vehicles waiting for anything! And once again I see no carhops delivering food/drinks to anybody! This is a common occurrence here and it is pretty frustrating! All I ordered were drinks which require no cooking! I have just about decided to no longer get my 2 or 3 drinks a day from this facility. I do not know how they decide who and when to serve orders to but I know their system sucks! Like I said this seems to be a common occurrence here and it is a bunch of crap!
