A combined LOL/WTF moment from earlier at work:
A manager asked me to spot him on the forklift but another forklift certified employee ended up driving in the manager's place, but the manager was there to oversee at first. This employee seemed to burn rubber with the forklift and at one point did donuts in the parking lot in front of the manager and I. Fortunately the manager was a good sport about it because he wasn't in danger of hitting anyone.
Two days earlier I oversaw my supervisor speaking with a customer because the customer was looking for an item that had been discontinued due to poor sales last year. At one point the customer asked if they could speak with a manager and he said, "I'm the manager!"
