Here is what I do no matter where I go for service. I sincerly thank the good employee for their good service (not many people do that). I am civil as I am able and when the employee makes a bonehead move or has a crummy attitude I ask again like I didn't hear or understand. Then about 50% of them will be nice. The rest confirm my suspicion that they are jerks and I tell them calmly that I don't appreciate their behavior. If it gets nasty, I let them make a fool of themselves and walk away with a smile. Don't let others dictate your response. This is a lot of fun and can head off some real nasty exchanges. Good luck. Remember that if you end up acting like a punk, you lose.
