One point lesson

What's in it for me?


This is a useful phrase to use when someone asks you to do a favour and you want to know how you will benefit from helping them. 


For example, your boss asks you to work back late and help cover the late shift. You are not really sure you want to do it so you want to see what they will offer to do in return. 


Boss: Could you do me a favour and do the late shift tonight as we are short staffed?
You: I worked every evening last week. What's in it for me?


This way you can let your boss know they are in your debt.
