I wish the Michael Kors store closer to my house was as awesome as the one at the Venetian/Palazzo!
The service here is similar to that of a high-end designer store at any of the shopping centers on the Strip - after selecting a wallet for purchase, I was brought a glass of champagne while I tried on jewelry. The SA, Matthew, was very polite and didn't rush me even though the store was busy.
During checkout, the cashier let me stand behind their register to fill out the warranty/info card so I'd have privacy (I doubt anyone would do anything with my name and address but y'never know!). My new wallet was wrapped perfectly in tissue paper and a small MK shopping bag. On my way out, several SAs wished me a "good day" and thanked me for shopping with them.
