Colleagues and appraisal

I have overheard this conversation.

One of the colleague who was speaking with another.

First colleague said " I am looking over your shoulders just to make sure you are working fine."

Second colleague assertively said "Oh, Yeah !!! Sure you can look over to check if I am working or not but make sure of you pass on part of your salary as a part of my appraisal !!!"

Enjoy...
