Does Bud think Herman E. Calloway is working him too hard?

No, according to Bud, the work that Herman E. Calloway had him doing was a piece of cake.

I know Herman E. Calloway was trying to work me like a dog, but he was doing a real bad job at it. I'd already wiped all the tables and chairs down in the Log Cabin and now I was going back to clear-mop the floor for the second time. It was a piece of cake! The bucket even had a thing on top of it that you could use to wring the mop out, and Herman E. Calloway didn't even know how much fun I was having. Making somebody work hard isn't as easy as it looks, some folks are good at it and some folks aren't.
