Loyalty reciprocation

Reciprocating for highest/best loyalty

While driving I caught my 7-8 minutes of sports talk radio with an interesting discussion on loyalty. The syndicated host of the show mentioned he has "stand alone" loyalty to his wife and kids. Nothing else gets his undivided loyalty.
The host went on to discuss that he does have loyalty to others and his work, it is just 'conditional loyalty'. He was separating 'conditional loyalty' from 'absolute loyalty'. He explained his 'conditional loyalty' at work reflects the loyalty his boss/owners of ESPN show him. In summary, this radio host was saying that he reflects the same loyalty he is shown.
This discussion got me thinking of "loyalty" in my line of work. But how does it start & how does it get on track for a great buying experience? My industry as it relates to "Agency" thrives on the degree of loyalty involved. Both principal and salesperson/agent/Realtor seek loyalty from one another. Through this loyalty comes open communication and trust. Good communication leads to great discussion which leads to informed decisions. Considering my line of work (an agent, Realtor for others through sales) it is interesting when I personally don't trust a salesperson through other endeavors. I know I have had obstacles to giving my loyalty with car purchases, remodeling jobs with contractors and cell phone stores. It even shows up when I am looking for a simple shirt at a store - "no thanks, just looking". If I don't feel a sense of loyalty from the sales person, it is hard for me to give it back to the sales persons. This scenario plays out to where I can't allow myself to be helped because I am not comfortable opening up with what I want and what I expect. This is a fascinating scenario for me because I am on both side as both the customer at times and the salesperson.
Have you ever had doubts about the loyalty towards a salesperson only to realize it was your own trust issues in general?
