Can you say something about the sums? I (in germany) got my rent money every month from my parents while I was a student. No problem. I withdraw something like 100€ per week for bars, backeries and other small expenses and I never ever had any problems.
It buffles me that so many people are jumping to conclusions although you provided so little context.
If you have a cash inflow of 50k per month and withdrow that much, the bank may think you pay people in cash, avoiding taxes (like on construction sites). Which is totaly legit IMO. But again, you gave almost no context..
I am really curious how this has proven to be an issue for you or if this is just another banks bad crpyto thing?
I think that's their choice. They can make that decision, and it's fine.
Why do you think you are entitled to demand a private enterprise allows you to use their services in any way you see fit without asking you questions?
Want to receive your salary? You need a bank.
Do you need to pay rent? You need a bank.
Do you want to receive social welfare? You need a bank.
As unfortunate as it is, banks have become a dependency for modern day living.
