Its always good to hear experiences like that, especially in today's retail world. I've worked retail in a jewelry store for over 11 years and we always get people praising our store and saying that they love shopping with us because we take each person seriously and have fun showing them around whether they're just killing time or seriously looking.
"Expect that each person coming in is buying today" is the philosophy I live by. By that I don't mean that I'm pressuring each person who comes in to leave with something, but rather that I give each person coming in my full attention and assistance. You'd be surprised how many times someone has come in in raggedy clothes only to leave with a $10,000+ Rolex or diamond ring.
