Seems like SAs are just like any other salesman except that they are surrounded by luxury goods, have to be knowledgeable in the goods and provide top-class service to the customers. Even their mannerisms and way of talking have to be taken into account.
The good thing about being a SA is that they know which is the latest stuff that had arrived. Some also say it's a good opportunity to meet young, rich bachelors. Lucky for them. Will love blossom?
