When the Chron polls readers for the best City department, the firefighters always win, but Solid Waste Services truly seems to have the most esprit. These people work with zip, even in the hottest weather. But our City-issued trash receptable suffered a big gash in the bottom. We waited two weeks for the new one only to find that the replacement, ostensibly the same size, has the corners rounded off and therefore has a substantially diminished capacity. It's also a flimsier gauge of plastic.
