My bank in Canada seems to only ever have $3K max to give out when I need to purchase a pin unless you give them days notice. Even then they seem to put you through the ringer.
Strange they don't seem to have a problem accepting as much as you want to give them, but when you want it back, even when they have done a big song and dance to prove who you are, they pretend the safe is empty.
I can appreciate some level of security, but two of the last three times I have tried to withdraw a large amount of money it has been a major hassle.
One of the better comments the teller made was "this is an unusual withdrawal based on you account history". When literally my account history is saving up some cash and blowing a massive stack on a new pinball every year or two. I did not feel like arguing with her as she was just trying to do her job, but I thought it was funny.
