Why do white collar (most office workers) make you wait or deliberately stall to see you?

I used to be a blue collar worker and had noticed that office staff would always make you wait for them. Even when they were not busy ( rarely seen them be busy) they would still keep you waiting at the reception area or waiting room. Some deliberately stalled or procrastinated.

When I had worked long hours in my area inside a busy warehouse, or on the road driving a heavy vehicle,I was always busy and made the time and effort to see someone in the office area. I never kept them waiting or deliberately stalled. I may have been a low paid blue collar worker but I was never late, nor did I take my time, gossiping all day, and chit chatting to the other hard working staff because it was a very stressful and busy environment. Not fair at all.

I have been going to job interviews for various organizations and prospective employers only to be kept waiting for long periods of time. In fact, I waited for a whole hour just to see an office jerk who spent only five minutes interviewing me. I had noticed that he had no one else to see and didn't seem busy at all except to chat to someone about a trivial matter.

Also, just because you are unemployed doesn't give them the right to treat you like a third class citizen even though they have a well paid job. An easy, air conditioned, plush office job! They are on a salary and not on a low hourly rate of pay.
