Unexpected profit - Should I give a kickback?

this is when you show up with a case of good beer. generally $50 isn't much to someone in business, but show them that you care by making the effort to go to the store and buy beer. if your not comfortable buying beer for them then a gift card for a local restraunt.

monetary agreements are tricky. if you give him cash, then it may be expected the next time you show up, and if you don't give him what he thinks is the correct value then you will lose that customer. if you still want to give him cash explain what happened, how you were able to spend more time and make more than scrap value, stress how much time and effort you had to put in to make the extra money, and ask him what he would expect back. and then give him what he expects. and either you will realize that your trading dollars for time or it will become a second source of income for you.

I personally have a couple $10 subway gift cards on the back of the stack of business cards that live in my cargo pocket, so new customers that I want to make a impression, or existing ones that need some extra encouragement, and I usually say something like, thank you for your business, today lunch is on me.,
