I respectably Disagree, I have been one time to the Reds Hall of Fame Grill, We waited maybe 45 minutes, and the serving sizes were decently Big. We used our Meal Plans, but at the end still tipped the waiter, as the atmosphere of it being a real restaurant made it feel wrong to not do so. As for Skyline, You walk through a line to get your food, it inst brought to you, If have rarely if never seen anyone tip the workers there since there is really No one to tip....
