Them: I'm sorry, sir, the tires you ordered didn't arrive, but we have these others.
Me: No problem, they're the same price, so go ahead.
Them: Actually, these tires cost $20 more per tire.
Me: No, really, they're the same price.
Them: Yes, sir. They're the same price.
@quix It didn't hurt that there's another tire place literally across the parking lot. :)
