If there was a £50 note lying on the floor, could you get out of bed to pick it up. If yes, then you are a skivving sissy and should be at your desk or counter or coalmine, whatever.
OT...
I was in a pub and an elderly Gentleman dropped a 20p on the floor. Looked at it and shrugged
A young lad next to him picked it up, and handed it back.
The old guy then explained that with a bad back, hips and knees picking up anything less than 50 p simply was not worth the effort
