I hired a contractor for a very-short term programming gig. But he claimed that he took extra time in doing it. And wanted a bonus.
When it came time to pay, I got an email reading :
Can you please tell me how much to bill you for this project (including the bonus)? I hope you are completely satisfied.
This bugged me some, because I wanted him to give me the bill amount.
I decided to guesstimate some amount, including a bonus. And later regretted that decision (I feel I overpaid him).
How do you deal with contractors who want bonuses?
