General Debate trading for a free stay?

So the question is what is okay to trade for a free night at the hotel. I was talking with my Buddy Cash at Orem Window Washing and he thinks that it is okay to trade window cleaning service with a free hotel stay. I am up in the air about it. I know I am on the conservative side.

I know people in the trade industry trade services with others so no money exchanges hands and the “man” does not take any of the pie. However the question is . . . How do you feel about it?
