I'm going from Berlin to Zurich by bus and I've just been forced to buy a full separate ticket for my viola.
Why can't I put it on a shelf like usual? Because if the bus driver suddenly hits the breaks then the viola might crash through and hurt somebody.
Why can't I put it under the seat then? Because if we get into the accident and would have to leave the bus immediately then the viola under the seat might become a serious obstacle.
That's why an instrument has to have a separate seat...
Fuck you, MeinFernbus!
