Quick Car story

So the other day, me and my sister decided to help my Mom multi-task. We had to run by the grocery store, get gas in her car, go to my grandma's and get dinner before a certain restaurant closed in a little over an hour. We decided we would drop her off at the grocery store and drive around the corner to put gas in her car. She has a nice, newer BMW. Not new this year, but newer technology that will soon become important to the story....

So, we get to the gas station and I turn off the car in preparation to put gas into it... And this warning message pops up, "Key signal cannot be found. Car will not be able to start again" (Not an exact quote) My Mom's key doesn't have to be in the ignition it just has to be in the car when it starts, and it won't turn off just because the key leaves the car, it just can't start without the key being IN the car. But my Mom had left the key in her purse and taken her purse with her into the grocery store.

Result: My sister had to walk to the grocery store (luckily it really isn't that far at all) and find my Mom, get the key, walk back and then we were able to meet her back at the grocery store again. We did still make it there before she finished her shopping so that much was good. :) but it was really funny at the time. :)
