The amount matters.
I, for example, from
scroll in an account (not on the card, it has bank charges), in National and in Piraeus I asked for 15 euros (yes, up to 15 euros there is no bank withdrawal), and they came in within 2 hours on the same day and I repeated it up to 3-4 times within the I've done it every day, except after 6 in the afternoon, which is where I imagine it matters if they're working, they'd come in the next day. At Alpha, where I asked for 5 euros (yes, that's the minimum amount so that you don't get charged bank fees), there it takes 2-3 working days.
