A: "You shouldn't park there. That space is only for handicapped people."
B: "They'll never check at this time of night."
A: "I don't think it's a good idea."
B "What's that under my windshield wiper? I just got a $100 parking ticket. Wow, that's really a stiff penalty. I can't afford that. Would you mind splitting the cost with me?"
"I told you not to do park there. Why should I pay a penalty for your mistake?"
