When activating a brick(Bank, Employment Office, PD, etc) there will be options. Typing one of these options will trigger next menu. To get a job, you only type 3 and then the job you want. The problem here is that people have had problems when it comes to getting a job. I havent seen it myself, or even replicated it, but I think it's an another add-on that mixes with the chat. The only thing to fix it is to look through the add-ons for the one that does this.
The first job you have is Tourist, which have no items when it spawns. Next update of RP Jobs will add Tourist the Printer. Just to ensure there is no wrong. Each job have its own equipments.
Caps doesn't matter when you type in your job.
