I have been put in charge of running some training seminars for co-workers from other departments. These training courses will be 2 hours long for 10-30 people and will be put on by either myself or one of my co-workers from my department.

Speaking with the organizer of the meetings it has been made clear that my performance is being judged on the "successfulness" of the courses that I put on. One metric for this is a peer review and Attendance numbers. It has also been made clear that "no funds are available".

From my experience going to any third party training courses, Water/coffee is always made available to attendees.

Do you think it is being unfair to the other trainers if I supply cold water/coffee out of my own pocket, to try and boost my own attendance numbers?
