I was an ATM engineer on a couple of contracts.
There used to be a way on some of the older machines for the poor (in spirit as well as cash) to score a free £180...
But it's more sensible to get organised and steal the whole machine as the criminals already know, and do, so I am really only bringing the honest & non-ATM experienced members up to speed.
Each of the cash cassettes holds £20,000 and there are four of them per full size ATM..
