I have a plan for tricking a restaurant and parking overnight on their lot.
You might get towed. Why this particular restaurant?
I really hate the bastard owner because I always get overcharged on my meals.
I'm sorry that you're having issues around billing, but deceiving the restaurant won't do anything to correct your bills. Seems like the most obvious solution would be to talk to the owner.
I don't care. I will do what I want since it's a free country.
There's nothing in the Constitution that guarantees your right to park wherever you want, nor does it allow businesses to charge more than the prices listed. If you're being overcharged, there's a simple solution: point it out to the waiter or manager who will then correct the error.
