I managed a gas station back in the late 80's/early 90's that had these. We would go hide behind a pump and untie the knot and blow into the hose and the bell would ring constantly.
Oh, and when a co-worker was taking a sh** we'd sprinkle gas on a paper towel and slide it under the door and light it up

There was a local guy who became a cop while I worked there, one day he came in and used our phone to order pizza so he didn't have to wait that long when he got home. After he left we called the pizza place and had them bring 10 empty pizza boxes to show up at his door. LOL.
I've got stories for days from that place.
