Try what I do.
The moment you walk in the finance guy's office/cube, tell him/her:
"Look, I am not buying anything you are selling. Let us sign the papers. I need to go in 10 mins."
Disclaimer: I'm just being sarcastic.
Next time bring a small small ball point pen and fill the cover with fine granulated powdered sugar. Anyways if you're in the room with the finance guy and after he's done with his pitch do the following in order.
- Twitch your right eye (if you can't then your left eye), still can't?..well twitch something then.
- Stand up from you chair
- Walk towards the office door and close it. If already closed pretend you're just checking its closed
- Facing the door proceed to lay a line on your wrist
- Lick it off but quickly make a snorting sound
- Twitch your neck
- Turn around and take a seat
- Pretend your phone is vibrating so answer it. Utter these words while your teeth are closed shut. "Handle it for me" and then hang up the phone like a boss
- Tell the finance guy "are we done here, I'm a busy man" or lady.
Done.
If he still gives push back you have 2 options. The quiet option. The hardcore option.
- Quite option. If he restarts his pitch stop him in mid sentence. Point you phone towards him saying "I don't have time for this". Repeat as necessary. Maybe leave some granulated sugar on you nose.
- Hardcore option. Lay a fat line on his table. Snort it. Pound you fists unto his table like a deranged lunatic screaming I DONT WANT TO PURCHASE A FREAKING _______ , I JUST WANT TO GET THIS OVER WITH. DO YOU UNDERSTAND ME!!!
Now if for some reason they call the cops on you ensure that you advise the cops your sugar levels were low and the finance guy was stressing you out. You might've made a scene. You might've even scared off other customers to leave the showroom. But in the end you did not purchase extra crap from the finance guy.
