Why are couriers miserable bastards?

hippy If it makes you all feel better even though email, faxes, digicams, etc have fscked up the courier trade, my company uses couriers for shuffling "we love you" type gifts to clients and suchlike. I think it gives management a buzz to be seen spending more getting things sent as fast as possible using couriers, rather than waiting in Royal Mail for a delivery that takes a day.
it's probably people delivering you chocs and bike bits!
