I remember once upon a time the higher ups pointedly polled us on how we wished to be rewarded for our work without higher pay being an option and the only non-intrusive answer was having your peers congratulate you. They made this system where you could "shout out" other employees. So I shouted myself out and got reprimanded. I then went on to buy donuts and campaign for shout outs. I offered to do work in exchange for them, bullied my friends into giving them, and went to other departments to network for them. The higher ups did not find it amusing.
Edit: my current work for the CIA has an element of sales to it
