Do you guys get pissed when an employer wants to hire you but tells you oh ur starting off as trial

Thank God I have never accepted this and refused to go. “Trial” like wtf .. I'm sure a trial is a day or two which is a complete waste of time. I remember this woman wanted me to work in her shop as trial. I was given no information as to whether I'd be paid. Like bye go waste someone elses time. Lol
