need to be standardised with the rest.usually it's card in, pin, ask for money, decline receipt, take money and card, leave.
post office cash machine - card in, pin, - all quite standard stuff so far. Ask for money, AND THEN IT ASKS IF YOU WANT TO CONTINUE. Always assume this is the receipt button, so always press no before i realise my careless mistake. Card pops out, moneyless, repeat the process ad infinatum.
Don't try the post office, folks.
