Where the Customer is Definitely Not God
The three brands pretty notorious for treating customers badly are Louis Vuitton, Chanel and Hermes (LV a bit less than the other two). Of course, there are exceptions and if you happen to come across a salesperson who is just innately a nice person you can actually have a great experience but generally the philosophy is off in these places. The idea behind it is to maintain that sense of exclusivity and keep out the "riff-raff" looking to buy just that one bag or some other item which will be the highlight of their life for the next few years. The 'real' luxury client, as per these brands, is the person coming in and spending thousands of dollars frequently through the year. That's who they want to cater to and you who have spent the last couple of years saving up your salary to buy that one piece or just walked in to check out what's new aren't really "worthy" of their attention.
Now Miu Miu is not something I would really want to buy any more of because they seem all over the place. It's Prada's little sister who is in the inner circle because of Big Sis's name but who's yet to figure out who she is and what she stands for. I like their matelasse designs and have a piece in the crystal line but I don't see it becoming iconic anytime soon. Anyway, they have introduced a new line of woven material and I just stepped in casually to see it. I would've been pretty ok with the SA ignoring me honestly since Prada folks can be unpredictable in my experience. But no. She looked me up and down three times as I walked in, much to my discomfort, and then pretty much screamed "What do you want?" as if I was standing at the door with a begging bowl oozing dirt all over the floor. In my experience, what works with rude SAs is being rude right back to them. If you try being nice or get uncertain they'll get more aggressive and make you feel worse. If you take a sense of authority and give them back what they are giving you they tend to mellow down. So I ignored her. Simply turned to the display with my back to her as if she hadn't even spoken. I could sense her confusion and wondered if she will call security but, after a minute, she walked over and asked if I wanted to see something. But the initial response had done it for me. Even if I had walked in with the intention to buy something I'm pretty sure I would've changed my mind after this.
Also, when it comes to customer service I've noticed a big difference between Indian and non-Indian brands. I'm not saying it's a country thing but generally with Indian designers and boutiques I've never really walked out (with the exception of the occasional bitchy-for-no-reason, stick-up-my-ass SAs) feeling like I should rethink my rights to this planet. People are usually fairly polite and helpful and actually make you feel like buying something. For that matter, I've experienced that SAs of even foreign brands are more polite and helpful in India (at-least in Mumbai). Maybe it's a general culture thing.
