Maybe they actually have a Worten company chef who knows what he is doing, or maybe you are just unaware who customer service should be. I don't know. The natives here (south of Spain) don't see that everyone is downright rude to you. Until you go to a scandinavian / north eu place and you see the difference. But it might just be the people here; there is a huge difference between the two.
I'm curious, what do you mean? Having bought from both stores (in Lisbon) I have noticed no difference.
Edit: never mind, I just saw your answer to this comment's sibling.
