I may be misunderstanding what you're saying, but who gets paid twice for their job? Allegedly UK MPs are mostly on the take, fiddling expenses, but that's another thing
The article refers to office situations, not service industry, where monetary tipping is commonly used to form part of the employees wages.
I guess I expect others to think the same way as me, which is probably a mistake. Because if someone at work does something well (this is a software team we're talking about), I make a point of saying "great job", because I appreciate their hard work and creativity. I just think that kind of recognition is wonderful to receive, because peers know the difficulties of the job, much more than managers, who by and large are far removed from technical details.
