Been there, done that.

Quick eye test, about 10 Chf. Than did a control test, about 20 min, pretty easy, only thing the examiner said "Because your car is dark color, I would suggest you always have your lights on, even during the day", I justed twisted my ahead around like that girl from the Exorcist and asked "Whatever ... now gimme my driving liscence!" We did speak english btw, and somehow I used that tactic "bore him to death with some cheap bla bla bla" slow him down, so that wouldn't t pay any attention to all the errors I was making, and rather get very desperate to step out of the car
