I would probably agree with the attendant if they told me "You were stupid for losing your ticket." I wouldn't think I was actually stupid, but being responsible for my actions is important to me.
Also, being adhd Ive accepted the bone-headed things I do/lose. It also wouldn't be a shock to find the parking ticket in the freezer a week later.
To them, it's irrelevant whether the helplessness is real or not. So they don't bother to take a moment to poke at the attendant's capacity for resolving the situation to their advantage.
I wouldn't say that its an unusual view, but it may indicate a deep desire for efficiency (don't argue, simply pay and be on ones way), financial privilege (an extra $20 charge is no big deal), or could be symptoms of deeper issues relating to self-worth (I am not worthy to ask for a break).
