Or, rules that seem a little silly
This is something that Big Dave pointed out to me today:
If you go to the post office, and buy foreign currency, with cash, they’ll happily give you it.
If you go to the post office, and buy foreign currency, with a debit card, they expect to see photo ID first.
But if you go to the post office, and give them your Link card, you can withdraw money over the counter, without ID. Even if you just hand that money straight back over the counter, in exchange for foreign currency. Even if you’re using the same card that you can’t use to buy foreign currency with, unless you’ve got ID on you.
What’s the point of that, then?
