My most awkward repair was when a customer's pet bird wouldn't stop copying the dryer buzzer.

That's actually kind of tragic from the bird's point of view, lol. It probably thought the dryer buzzer was another bird trying to talk to it, and then you showed up making all kinds of weird noises fixing it. Now the poor thing's whole social life is thrown off. Bet it started mimicking your power drill next just to keep the conversation going.
