Just be very, very careful what roles you express any level of interest in. Even if you express low interest, you can end up in that role, and you may be miserable. My son is down doing custodial right now, has had one street shift and loved it...gave directions, took pictures, did pin trading. Other than that he has had, and is scheduled for, only restroom shifts. 6-6.5 hours a day, by himself, in a restroom. Yes, he knew that was part of the job. However, it has turned out to be the only thing he and the other CPs in his area are being scheduled for.
