Well......truth be told - I didn't actually wash someone's car. I did the next best thing. While getting gas the other day, I noticed the car next to me, and the kids in the back seat asking mom to take them through the car wash (as do my kids). While mom was having none of it, I sprang into action and presented her with an Ultimate Deluxe car wash receipt from the cashier. Kids-1, Mom-0 ;-)
