Annoying things that people say

A question for the autsitc people on the forums:

What figures of speech or expressions really bug you? For me its when people say 'You're joking!' when I've just told them something serious and am clearly not joking.

For instance I'll tell my boss that a bit of equipment has broken down and what does he say? 'You're joking!'. Why does he keep doing this, there's nothing remotely humourous in what I've said and I'm waiting for his instructions on what to do! And its not rhetorical because he waits for a response after saying it and I then say I'm not joking.

Another pet hate is are 'How are you?' when the questioner doesn't really want an honest reply.
