I don't know how this works in the US but here in Germany your work contract roughly specifies what you do for work.. so for a software engineer it would be developing software and similar tasks.
Cleaning break room fridges would not be an acceptable task. You sure could say yes and comply if you like cleaning fridges but usually people would probably just say no thanks.
If you just exaggerated to make a point I agree with you partially. But you always have to consider your personal growth and satisfaction with your work.
