Well, glad all turned out okay. I know if I did that, I'd never ever hear the end of it from hubby
My best friend did this years ago. She took her two small nephews to the Philadelphia zoo. Got out of the car, went into the zoo and had a wonderful time. Came out, couldn't find her keys. Finally realized that she had left the car running with the doors all locked up

She didn't have AAA so she called a tow company. They wouldn't come unless she had the cash, all she had was her checkbook. The guy was really a jerk about it, and here she had two kids under 5 to get back home in New Jersey. So she told him I'll get you the cash when you unlock the doors. She wrote him a check (it was good, she just had no cash left on her) and told him to take it and shut up
