I must be stupid

I must have stupid across my forehead, the guy shows up at my door telling me that there opening a new office so there giving away one free room of carpet cleaning that I can't pay them or tip them. I think sounds great. Instead I end up with the guy here for 2 hours trying to sell my a $3000 vacuum. I guess I at least got the carpet cleaned but for listening to him for 2 hours he could have cleaned the whole room not just done a half way job.
