Steak 'n Shake Enterprises — slow service and missing orders

When i received my order we were missing a chili and a salad and a strawberry shake the service was bad real bad but the time the 3rd order was at the table almost everyone was done eating. The fries was cold had to ask the waitress for my ticket 3 different times talked to the manager he acted like he didn't care i thought that the manager is supposed to be there for the costumers
