"I just didn’t want to deal with all the complaining." I can definitely relate, but it is what you're getting paid for.
See also "Give Me a Better Grade--I Deserve It." I got one of these last year. A student objected to my suggesting she write more concisely. "That's not how I was taught to write," she said. "I should just get a higher grade."
It was one more indication it was time for me to retire.
