A: Excuse me, sir?
B: Yes, is there a problem?
A: I'm sorry to be the one to tell you, but you can't park here.
B: You mean right here, where I just parked?
A: Yes, unfortunately you cannot.
B: Oh, I was not aware that you couldn't park here.
A: That's alright. It's a common mistake new residents often make.
B: Thank you for informing me.
A: Not a problem. I wouldn't want you to get a parking ticket.
B: That's so considerate of you. Thank you.
A: You're welcome. Just keep it in mind for the next time.
B: Don't worry. I won't forget.
