Opportunistic
When I was much younger, we lived pretty close to a supermarket. They began running these scavenger hunts for crappy kids' chocs called 'Yowies' (I think). Realising that I was on to a good thing, my siblings and I would routinely raid the supermarket for these freebies before any other kids got to them.
Since the shop clerk who ran this was beginning to look askance at us, we became a bit more circumspect and tried to limit our takings and allowing other kids a chance. But really, we owned the whole thing. After maybe two weeks the shop clerk blew his top and ordered us off the promises and out of the running.

The OTHER barring we got was at the same supermarket, this time in the loading bay area. It was like a skating rink in that it had a gentle bowl-shaped incline and was surrounded by three walls, as well as some awesome rounded mounds which you could jump on your bike. So we began to use it quite often.
The guy who ordered us off was some super trolley collector who went around the car park in his restricted-to-15km/hour (so he said) ute and collected all the trolleys. Apparently he was worried that we would get run over by him as he and his super-fast juggernaut would invariably make mince-meat of us. We thought he was joking, but when he offered to call the police if we didn't get lost we got the idea and went. Idiot... we still used it, just after dark when there wasn't anybody around.
