Swiss Banking Rules: Reason #2

So today, I went to the bank to withdraw the first month's rent for our apartment. Seems the owner always wants the first month in cash, and all subsequent months can be a direct transfer. I gathered up all my identification before I left for work for the day so I could run out during lunch and get the cash. It's a large sum, as far as a wad of cash goes. I felt weird just asking for it at the bank. The process is this: tell teller you would like to withdraw a large sum of cash. Teller says to enter your card into little card reader and enter PIN. After doing so, teller gives you the cash. No identification is required.
