I can tell you from experience that there’s a 90% chance she absolutely was trying to draw you in to sell you something
I used to try to politely decline, now I just wave and say I’m not interested. If they try to change the script, “I’m not selling anything,” I just repeat myself and they get the hint. I used to feel bad, but then I realized it saves them and me some time, so I’m probably doing them a favor.
