1. My swiss German is now pretty fluent - I understand 99% of what is being said by 99% of swiss people. Most Zurich CS people will ask "Is swiss german okay?" when they hear that I'm not swiss
2. CS is an international company
3. I cover about 20 different projects / courses and send and receive a LOT of emails a day - usually about all 20 projects
So I kid you not, today I get a phone call (in Swiss German) that goes like this
Her (swiss German speaker): I'm ringing about your email
Me: Okay. What is it concerning?
Her: The email that you sent me
Me: Fine, but what was my email about?
Her: The course
Me: I'm sorry, but which course?
Her: Excel of course
Me: (takes deep breath)
Her: Rambles on a great length, something about the course that she might or might not have signed up for and is it the right one. In very fast swiss german
Me: I'm sorry, I still don't quite understand the context and what you want me to do
.....finally I work out that she is asking which level excel course she sould do
Me: Okay, well, could you tell me what you currently use Excel for in your daily working life?
Her: No - now talks even faster now in swiss german. About cancelling the course
Me: I am very sorry, but I don't quite understand. Could you speak a bit slower for me, or could you switch to high german?
Her: WELL IT'S A SHAME YOU LIVE IN SWITZERLAND IF YOU CAN'T SPEAK THE LANGUAGE
Me: (Flabbergasted. Bring the call politely to an end!)
