Boris,

Absent any other information about the customer, the higher the quality and price of the item in question, the less presumptuous the salesperson has the right to be.

If I walk into a shoestore with $300+ shoes on and indicate an interest in buying another $300+ pair, the salesperson has no place suggesting to me in any way, shape or form that I don't treat my shoes in a manner that suits my own best interests. If I want to trash 'em and buy a new pair every month, then that's exactly what I'll do, and it's my business, not yours.

To imply otherwise is to make the customer wrong, which of course breaks Selling Rule #1. Always a mistake, but especially a mistake with people with money: they generally have larger egos, and rely more on their own judgement than that of others.
