My husband and I loooove Sonic, but we have to go about 20mins away to get to one. We don't tip. I think tipping has become too commonplace these days and I only do it when I know that the person has "taken care" of me. Walking 10 steps to bring out a bag of food isn't anything over and beyond their job. Then again, maybe I'm just bitter because I don't get tips at work!
