Guest post by "Lukkai" Truly, the only horror story I could tell from Switzerland is the prices they used to charge. But that has gotten better over the years. It's still quite expensive, mind you. But better than it was.
About that store you mentioned though. These times I wouldn't leave it with walking out and never going back. I'd also use mouth to mouth propaganda to share the story. And see if the store is mentioned in some network with the possibility to leave reviews. Even if it's on Google Maps or something Then put in a negative review with the exact specs of what they did wrong.
