I used to build my own jurassic park in lego when I was young.
Since the first set I've been buying them all, I just need to visitor centre.
Not sure where I will put it since the display is getting very full.
In the Netherlands could always take money from other machines. These are called guest transaction and where free but only allowed once a day.
Since the maintenance and upkeep is expensive some banks decided to co-operate the cash machines. Since all transaction go via a central system. Even if the machine is from your own bank. This central system used to be owned by the banks, but this might not be the case any more.
Do to privacy laws banks can not just check into your transactions, if they do and get caught the fines are huge. So I do not think they would risk it.
