When I lived in cranston i had this issue. I was over by the Cranston parkade. There seemed to be no rhyme or reason for it. Waste management always insinuated it was somehow my fault, much like everyone else here said they were out on time not over flowing nothing blocking them ect. I stood outside once and waved at the driver and asked him if everything was ok with my cans ect and told him what was wrong he comfimed all was good and never had an issue again.
