My SA told me that they specifically look for clients that will become "lifestyle clients" and can tell when someone is just trying to get a bag. My SA also said that they will not sell a walk in a bag if they don't see any long term potential.@parisistherapy and @acrowcounted I will also admit that I am skeptical of how that practice works in reality. At the end of the day, SAs are there to make as much money as they can for themselves and for their stores. The comment about trying to feel customers out sounds more like something they feel they should say than how they actually operate.
edited to add, this is just what they told me. I don't have an opinion on it.
