Same here in Hat Yai, daily collection, the bin men usually come down our soi between 2 and 3am, but by that time several scavengers will have been through the bags looking for stuff to sell. Some are fairly tidy, but we've one old guy who just rips the bags open, throwing stuff everywhere, looking for old clothes, metal, plastic, paper or whatever takes his fancy. The bin men are good at collecting it all up, but it makes their job harder.
