Do NOT let Kirby vacuum salesmen into you house. Even if they tell you they will clean your dirty, spotted carpet in your hallway. Even if they tell you it won't take long. Even if they tell you are under no obligation to purchase anything. NEVER.
They will stay for 3 hours.
I know from experience.
They wouldn't even leave when we all sat around the table for dinner.
They wouldn't leave when we told them that we weren't going to buy their 2000 dollar vacuum (32 times).
They might even make your house smell like cigarette smoke.
Just don't let them in.
