A collegue that used to work in my service took the right shoe of every drunk he went out to and disposed of it, although im not condoning this action whatsoever, the cost of a new pair of shoes did punish them in both pocket and soul (see what i did there). as for tiredness my wife who doesnt work shifts just would not accept that they "screw you up", until I had six months off with a back op and then she noticed how i was awake past 9pm and everso more cheerful :)
