Yes, but that works at <i>your</i> branch.<p>If you were to walk in to say the New York city branch of a major bank that you have an account with in the countryside then you'd be looking at a completely different situation.<p>I once borrowed E100K from my bank just on my promise that I would pay it back within 7 days. That would have been a lot harder if I had not been a very good customer of theirs for more than a decade.<p>But I still doubt they'd let me past the 'no customers beyond this sign', simply because they have a duty to safeguard the privacy of their other customers, even if we'd have a higher than normal level of trust between ourselves as people.
