I think bin cleaning is something that is concessionary spending, when times appear hard or money is tight this is the first type of thing to suffer.
Many will opt to do it themselves.
I had a bin cleaner, but he did nothing to keep the business, clean the bin, drop off the invoice. Sometimes people enjoy a freebie a something extra, perhaps clean the other bin once in a blue moon. He didn't offer anything I couldn't do myself. Just a thought. Not being anal!
