Sometimes when I'm on a job for my dad fixing a furnace or a toilet or something, we get customers who just breath down our necks constantly asking questions like, "What are you doing? Why are you doing that? Are you sure you're doing this right? What does that do?" and it's so forgetin annoying because we need the space they're taking up to put tools and stuff (you wouldn't believe how small some people's bathrooms are, and they get even smaller when there's two people and a bunch of tools in there) and it's just aggravating.
