True, which is why I said “might”. Even in the US. I only have to call ahead if I want smaller bills - $20 and $100 they usually have plenty of unless it’s a tiny branch.

Cash deposits or withdrawals over $10k in the US will be reported to the Treasury but if you don’t do them often it won’t raise a big flag, and the bank doesn’t care what you do with it. Treasury only cares if they think you are trying to evade taxes.

In Germany, where large items are often purchased with cash, it would be unremarkable if you did it several times a year.
