You said walk-in withdrawals. Which sounds as €3,000 each time you literally "walk-in". What does "walk-in" even mean in this context?
It was not me who first said about walk-in withdrawals, I just repeated in my words what I had read at the link I provided. So, I guess, everyone curious should go and read it. I think "walk-in" here means that you visit a bank in person and (try to) withdraw cash as opposed to wire transfers. In this manner, €3,000 obviously refers to the withdrawal limit per day...
Do you happen to live in Greece or ask just out of idle interest?
