trash anger

So we have some neighbors (possibly several different people) who, for the past few weeks, have decided that it's too taxing to lift the lid to one of the two dumpsters here and instead have started just dropping their garbage off right in front of the dumpsters.

WHAT THE FUCK.

STOP DOING THAT.

WHAT

WHAT THE FUCK.

How can I punish these people.  Throwing their trash away for them so I don't have to look at it doesn't teach them anything, and leaving a bitchy anonymous sign is... bitchy, as is talking to the apartment manager.  I SEE THEM DO IT.  They just stroll out there and toss their trash half-heartedly at the dumpster area.  FUCK YOU PEOPLE.

These are things I get really angry about before I've smoked.
