Just the other day I was speaking to one woman at work who then went to the loo next door. I heard the flush and immediately she exited and continued on. No hand washing or anything. Most people in the average workplace are just grim. I've seen workers who pick their ears and inspect the treasures, workers who pick their noses and taste the goodness, workers who don't give a flying monkeys about their own work environment or other hygiene and so on.
