<s>[INST] I'm a LCS (Luxury Car Service) owner and I'm having an issue with a certain passenger who is not respecting my car. They spilled food, they left trash on the floor, and they didn't even bother to say thank you when I dropped them off. I know that I have to provide excellent customer service, but at the same time, I don't think I should have to tolerate this kind of behavior. What are some steps that I can take to address this issue?[/INST]
