I was the proud owner of a new car (one Friday Afternoon):

A few weeks after buying my new car, I was driving home from work on a Friday, and stopped about 20 miles from home to get gas. I locked the keys in the car in front of the pump, with the engine running.
The gas station people were very nice about this. No problem! One of them felt along the roof of the gas station and pulled out a long, wicked looking flat tool. He shoved it down the outside of the window into the bowels of my car's front door, and - dropped it inside the door of my car.
"Do you have another one?" I asked.
"NO!" he said.
I started to get nervous. I could wind up with my engine going dry AND not getting home for Shabbat. The gas station owner started making calls, and twenty minutes later a guy showed up with an identical tool. This time he was careful; they opened the door, retrieved the other tool, put some gas in my car, and I just beat candle lighting time getting home.
