The metal stairs here at work are super-slippery when it rains. There are yellow signs on each level saying "slippery when wet", with the classic bobble-head man going "whooooooaaaa!" Steve, my boss, decided that wasn't enough, and asked the centre maanagement to do something to fix the problem. I think he had in mind some kind of non-slip coating, some GritStrips* perhaps - something involving a guy in overalls putting in a few hours.
The Arts Centre people had a brilliant labour-saving idea - just tape another sign to the first one. I guess that's why they get the big bucks. Stairs are still super-slippery, but.
*I just thought up that brand name - what do you reckon?
