Dear Ms Derringer,
We have just wired the credits to your personal account. Good job.
Dear Ms Sarita,
You have not claimed a single kill during the trial period. We believe that this is a sufficient premise to deem you unfit for the job. However, you're free to reapply in several months when you get more proficient in killing space filth of the Liberty kind.
Mr Peyton,
If you're still alive after the last encounter with our operative, we wish to inform you, that we decided to punish you in order to set an example for other mercenaries. Never bite the hand that feeds you!
