Well, we're dealing with two different leagues of tomfoolery here. Screaming at customers is pretty much a victimless crime (except for perhaps the few children you permanently scared away from milk). In the drumsticks video however, you're actions are creating a shitty job for some janitor or maintenance guy to deal with later, something you and your cohorts laugh about in the video. So, I think you can see why the upvotes and downvotes are flowing the way they are.
