Don't you just hate people who use those 'hands free' mobile phone thingies that stick to your ear - I mean hate people who use them when they're not driving?
People who walk along with them stuck to their ears and carry out a phone conversation (usually shouting) on the street or in the workplace for example.
If they're near to you when they start having a conversation (phone call) you can actually think for a moment that they're actually talking to you.
This has happened to me several times - ie: someone near to you (it's particularly startling when you don't know the person) starts saying the like of 'oh yeah well I told him to just sod off and he said to me...' and when this happens you sort of jump and say 'oh - what - pardon!' then you realise that they're actually on the fuckin' phone!!
Annoying arrogant prats.
I feel better now.
