Refuse refuse

There is something I don't understand.

See, the problem is like this. Every Monday the refuse collectors collect the waste from my area. Unless of course, its a public holiday (we call it Bank Holiday here). Then it won't get collected for an entire weeek. Like duh, right?

So why is it that my housemates dump their bags of trash outside on a Sunday, knowing that it is a public holiday and that it won't get collected? It leaves a bloody eyesore for the rest of the week. (We're supposed to dump any garbage bags between Tuesday- Saturday in the basement collection area)

Are they just plain bloody stupid? Or are they ignorant and don't give a damn about the rest of us? This is not the first time.
