I was speaking of the suggestion that it's a normal, accepted practice. If people thought it was, then they might unfairly assume or suspect of it of many salespeople who do not do that.

you write "unfairly", but you probably mean "incorrectly"

there is nothing unfair about people assuming or suspecting things, we do not regulate each other's thought processes.

I see your point, and I could agree to "incorrectly", but would you agree that assumptions and suspicions tend to affect behavior, which would be when the "unfair" comes in?
