Working at McDonald's do you ever get abuse for selling unhealthy food?

When I did work in McDonald's that wasn't the case, the main problem was unfounded complaints, people trying to get refunds and extra food when there wasn't really a problem. So much so that we started writing complaints in a book with names and if we saw the same person making the same complaints over and over, they were told that we are onto them, then we'd get called every name under the sun because they know they can get away with it.

Nope. Because that Unhealthy food is being Voluntarily asked for by stupid people. 

They should start selling greens with junk food. Thank you for helping people with hunger but its not health in long run.
