Well I'm with Old Bird and co with this one. If you can't stand the heat don't get a job in the kitchen.
Of course being a cheeky boy I would be chasing for some free rent for my trouble.
Light stuff, plastics etc. can be simply gathered up a bagful at a time, taken away and given back to the Council via wheelie bins, and combustibles have a habit of catching fire. Metal, when dumped outside the gate tends to migrate onto totters vans. That just leaves rocks and brick. These should be used to fill any potholes in the roadway to generally improve the site. They also make useful paths if there is enough.
No excuses, get on with it. The more you all moan and bitch about it the more the rent goes up. The average plot is worth at least 10 times what you pay so be thankful you're not bottom of a 5 year waiting list.
