How about a hack for Mickey D's?
Obviously I do not eat at McDonald's and it would be maris ayin for a religious Jew to step inside.... but here is how I would do it if I had to do it (a la OJ's book title.)
You go in, you order meal. Get whatever you want that you can fit in one bag (this will be important for when you grab the bag and run.) At some point in your order, you have to ask for a coffee. Preferably a large coffee. Loosen the top of the coffee nonchalantly while he is ringing you up. Then, when the cashier is done ringing you up... THROW THE COFFEE IN HIS FACE... then grab your bag of food and RUN!
That's how it would be done.
