Rude, condescending staff. It is extremely disheartening to have some half-literate, barely qualified clerk in a temporary position of power to treat stressed people that way. Constantly kissing their teeth, telling people "Why aren't you working? Anyone can find a job now!". Do you know how discouraging that is to hear?

They act like you turn up there with a hat in hand, asking for their personal money. I usually pay more in tax than their entire annual salary is, but had to deal with them for a couple of months, and was just generally disgusted.
