I'm not cazy about the burgers either, but that Brown Bag Special is hard to beat. I ask for tots instead of fries, thouugh.
Drinks-Cherry limeaid, java chillers. Looks for happy hour 2-4 or 2:30-4:30 for 1/2 price.
We really really like the cheesesticks, popcorn chicken, jalapeno bites. I like spicey so I add jalapenos to anything-burgers, coney's, tots, etc. You can get extreme tots here that I like that are tots, chili, cheese and jalapenos. Super sonic burrito's are good, also.
Now, I'm hungry....
We do tip those teenagers, esp. since they work regardless of the weather. They get extra if it's cold, rainy, etc. Why would you tip a server at a buffet and not them. It's close to the same to me. You should be able to expect a refill of your drinks at the buffet, but then you have to go pick up your food, also.
