Depends on the organization and what they are selling. Usually, the best sales agents do not lie and just are darn good at what they do. Usually, it's the guys who can't really sell that will cheat and lie to their customers or take sales away from the new guys.

I'd suggest there are many doctors who lie and work the system when it comes to diagnosis and prescription recommendations.. why? Who knows why people lie, but the reality is Doctors are no worse than salespeople.

It's like saying all politicians are liars and if you agree with that statement Ozy then why do I see you defending
the left often? Because I could generalize and suggest all Democrats lie all the time.
