In the other room two dozen salespeople are spraying, poking, pounding, and extracting carpets. It’s really cool. Each carpet sample has a different stain — gum, blood, various dirts and liquids. And they have a regiment of chemicals of various types and designs that they can use. The trick is to determine the spot, put down the right countagent stuff of the opposite pH value (indicated by the stain changing color), “agitating” the stain (pounding the shit out of it with a brush) so that the product does it’s work, and then applying enzymes and such, followed by drying it all (extracting the liquid). All the various chemical smells tickle the senses. The raw energy in the room is electric, and the competition to see who finishes first is leading to delightful shenanigans. This is a cool training!
