Visualise the sceneario:
It's about 6 or 7 pm,you've had a few,you've run out, either through bad planning or plain alcohollism and you fancy some more,there's no offy within walking distance.Ofcourse as we are all ahhhhmm responsible citizens - the car's out.
Therefore - (to make money out of these unfortunate individuals), buy an old van,buy a bloody skip load of cheap booze,some storage,advertise a home delivery booze service with a hot line emergency phone no. All at vastly inflated prices ofcourse.This should make you a million pounds within the first six months.
Hell,if I wasn't already on the rich list,I might be doing it myself!
AH
