Man, I gotta disagree with the idea that the rack is what saved your Tuesday. Fifteen minutes of setup time sounds great but a bent wire rack does not add 45 minutes to your prep, something else was going on there. You said yourself you were still breaking down chickens at 10:45, that is a scheduling or par level problem, not a rack problem. A sheet pan rack just holds pans, it does not chop, season, or cook anything faster. I would figure out why your prep list is running that late before dropping another $40 on a second rack for the walk in. The cheap ones do bend and rust at the welds after a year of daily use, so if you buy another, get one with welded corners instead of rivets. But fix the real issue first.

Same thing happened to me. Spent months thinking my chair was garbage and my back hurt because of it. Turns out my desk was just too tall for my short legs. Dropped it down a couple inches and stuck a old wooden crate under my feet, done. The crate was free and the pain was gone in a week. Weird how one dumb little fix beats a $300 chair every time. Chair people never tell you the desk is the problem.
