Just by yourself today sir?
Sometimes you need a bit of quiet time, don't you sir?
Well don't you worry about it sir.
It was awful. He used the word sir at the end of every single sentence. That kind of thing might make you feel comfortable and relaxed if, for example, you're sitting at the table wearing a suit of armour. But here in Australia where we're all descended from burglars and scoundrels, calling someone "sir" is a slap in the face. It's Australian for "I am required by my employer to show you respect even though I have none to offer, so I'll call insolently call you sir instead".
And the way he commented that I needed a bit of quiet time - that made me feel like a frail little child, unable to cope with the hubbub of the real world.
What really pisses me off is that he was right.
