Drifting on supermarket parking, possible penalties?

Hello because it snowed a lot in my place today I came up with the idea with a buddy to drift something We have there a supermarket parking place where is quite popular because it is optimal from the area to drift (: It was about 10 pm and the market was of course shot and no car was there. After about 5 minutes a local came and only asked to stop, because his children want to sleep and the humping of the engine makes too much noise. So we did that too and have gone away again! But now to my question it is possible that this local resident created an ad while drifting again? Or what would happen if the police came and picked us up in the parking lot? Would be very grateful for a few answers.
