I like Vienna for so many things but you have to love the customer service ethic that pervades all Viennese service professions, including in the doctor's office (chuckle!)
Here's a real exchange - translated into English from German - between a patient (P) and a front desk attendant (A) that I witnessed today.
P: Excuse me but I've been waiting for over two hours. How much longer is it going to be?
A: (somewhat agitated) I'm sorry, we're really full today.
P: It's really too much. Other people have come after me and they're alredy finished.
A: (really agitated) NO, THAT'S NOT RIGHT. THEY CAME AND THEY WENT AND THEY CAME AGAIN.
(P walks back to waiting room, A walks around corner to lab, comes back after finishing something, and yells at P who is no longer in sight...)
A: ARE YOU GOING TO STAY OR ARE YOU GOING?!?
(No response from P. A waits and waits and waits and finally returns to her business.)
