Not all companies are as jolly. When I was a junior programmer at a ------ manufacturer in Toronto, in 1972, I accidentally cancelled a job running overlong, thus damaging the program library. Dumb stuff from the dumb guy. No forgiveness. Out on the street the same day.
My first thought is whether it can still work its magic with smog, dust particles, bird dirt, all layered on the surface. Or are we going to have to wash our houses, instead of letting Mother Nature do it?
