Gotcha!

I picked up my car this afternoon after its two-day stay in one of our local auto-body repair shops. They provided stellar customer service, not a single delay or glitch. I asked the office manager for the name of the owner, because I wanted to write a letter singing their praises.
She thanked me, gave me the name of the fellow to write to and then handed over my key and told me where my car was parked.
"You probably won't recognize it," she said. "We washed it."
Ouch!
The other person in the office looked over at her.
"There goes that thank-you note," he said.
