You're fucking joking, right? It's free douchebag. Just take the keys, drive it, and be happy. Damn 20 somethins' thinking everyone owes them something. Thinking that they should be driving the Jeep Grand Cherokee Laredo 4x4 with Sirius, GPS, and a DVD player so that the kiddies in the car seats in the rear can be entertained. Get real, ya mutt.
You deliver samples of products that were approved by the FDA. You get a receptionist to sign an electronic device. You also deliver food. That is your job, nothing else. Take the keys, fill the gas tank, call Boston Market, and deliver that lunch honey !!!
Now that you have your answer on a ridiculous question concerning a "free" car; get out there and go to Dunkin Donuts for the morning call and hit the Panera Bread for the lunch appointment. Keep all those slobs happy; you caterer.
