I'm from the Netherlands as well, I had one bad experience in Amsterdam when I was buying an agenda there, I was literally the only one in the store and no one helped me, then after 10 mins the SA asked if she could help me, I told I wanted the agenda, I paid, she wrapped it up and that was it. But other than that I've always had nice experiences there, what did the SA's look like? There's this blonde woman who is somewhere between 40 and 50 years old and she is so lovely, and I was at LV last thursday and there were 2 sweet asian women who asked to help me. It's so different, I didn't have any of my LV bags with me, I had this invito bag (that everyone in the netherlands has lol) and they were just really nice. I have no idea what it depends on!!
And the way the manager reacted is really rude! I don't know where in Netherlands you live (ik in Noord-Holland en Zuid-Holland, afhankelijk van of ik bij mn ouders ben of niet, dus Amsterdam is voor mij de enige optie), but Antwerpen seems to be a really great store, so maybe you should try it there next time because I can totally understand how an experience like this is enough for you to be done with that store for the rest of your life! The SA's at Chanel in the pc hooftstraat are grumpy rude women as well btw
