That set off the SJWs that didn't have to deal with the messes left by their bums.
Some restaurants and grocery stores were doing that around here, just a few years ago. The reaction from the SJWs, and their ilk was just what you would expect.
The restaurants did it to avoid ruinous lawsuits, in the (inevitable) event a “binner” got food poisoning. The grocery stores were (and continue to) donating all their good, but slightly stale food to local food banks — so that only unsafe food was thrown into the dumpsters. That didn’t protect them from the wrath of the SJW.
