Yes correct when you do cash back at the register I'm pretty sure that's also changes the transaction to be flagged as an ATM withdrawal these days.

I know it harkens back to writing a check over the amount and the store handing you cash, but that's a Bad Thing To Do™️ these days because it makes it easy for a fraudster to pull more cash from your account than the daily ATM withdrawal limit enforced by your bank. Fraudulent charges can be reversed, but cash... 🥲

I can't remember ever doing that so I can't look up any transactions in my account to verify how it's flagged, though.
