What's the most descriptive adjective available for the way a salesperson acts when they are paid on commission? "Pushy", "smarmy", "self-centered", and "disingenuous" all come to mind, but none of them really paints the whole picture. Would anyone care to suggest a candidate?
Obligatory example sentence:
"I found the interaction off-putting because of the persitistently and unmistakably ________ behavior of this stranger towards me, despite this being a social occasion"
