A binner’s business—if you can call it that—is with the recycling blue bins and Dumpsters outside of apartment buildings.
What goes on inside the buildings is normally none of our business but word does leak out. Binners naturally get to chatting with building managers and tenants. Pleasantries are exchanged. Grievances are aired.
Tenants mostly complain about their rent and the upkeep of their suites. Building managers complain about tenants, tradespeople, and garbage.
Garbage problems can be a particular sore point because they can mean a visible mess, which reflects poorly on the building.
