• As a former Hermès employee, I saw customers make some common mistakes when shopping in-store.
• It's important to understand that most shoppers can't just walk in and buy a Birkin bag.
• Customers should have a good relationship with their sales associate, but they shouldn't bug them.

I spent two years working in retail marketing and visual merchandising at Hermés.
