Orange Safety Gear.
The H&S fellow didn't take the elevator. Okay -- overall stats actually prove elevators are safer than stairs. (No, pretty much *everywhere*, there are a couple of exceptions but they aren't G20 countries, I've checked, don't ask why). I claim that the H&S fellow was a millennial with GAD, on three types of medication and carrying an exotic, expensive overtorqued vape device.
Hiding in a dark corner and saying BOO! at the appropriate moment wasn't needed. Just being in the stairwell would have sufficed.
YAY! friday BOFH. Now, how many LPAR migrations from 6's to 8's can I get away with scheduling each weekend.
