Pick your revenge for the garbage people.

All that junk they're surrounded by should burn very nicely so I'd barbecue them all.

Feed them to a large group of walkers, kind of like the ancient "fed to the Lions" reality.

I hate those backstabbing creeps!
Start a gigantic fire outside the refuse yard
As they pour out to battle the blaze have your best gunmen in the woods (at all compass points) open up with concentrated/one-shot/one kill fire (.30 cal/5.56 will do just fine for this and Ricks crew has plenty!) Then, kill anybody that has any balls left with shotguns...figure 5-15 yard range
Next, line up all the survivors...shit is about to get fun-keep their sexy boss lady as a house maid...basically beat/and bust one of her knees so she wont be a prob-make it so she cleans your house and stuff-as for the rest of her messed up crew-
bury them all alive with a 'dozer in a trash pit in their own junkyard
Line 'em up at gunpoint and kick them in one by screaming one
Resistors get blasted point-blank...
It would take weeks for them to all suffocate/starve in that stinky garbage-hole
Its what the 'heapsters' deserve for F'ing with the wrong people

I feel like not enough people get skinned alive on this show, so let's go with that.

Best way to deal with the garbage people would be to write them off the show and lets all pretend they never existed.

Force them to take remedial English language classes.
