A guy I know was looking for a static security guard to look after a new mobile home until Monday morning. The hours were 9pm tp 9am and he offered £10 an hour.
I told him I couldn't do it but knew someone else who was reliable and might be interested so I rang a friend.
About an hour later said friend rang me, thanked me and said he owed me a bottle.
I said fair enough but even at £120 a shift it wasn't all that big a deal.
My friend replied saying he had renegotiated the offer to £15 an hour and I said "You'd better make that a couple of bottles then"
