Burger King

We were waiting in the drive thru waiting for our order. A huge delivery rig drove into the drive thru lane & smashed the left side of my car! It's totally unsafe to allow the delivery truck drive into the drive thru lane! My car is so damaged that I couldn't open the door or close my window. I have to pay for a safe garage to keep the car at night until it can get fixed and I have to rent a car to work! Who's responsible for the time and money I lost from this accident? Burger King or the delivery company?
