Signs Around Town: NYC

What does this even mean?

Did someone sue them saying, “Yo, now look here Miss Manager Sir. I bought this Big Mac Extra Value Meal and now there ain’t any seats for me to sit down and eat. I’m gonna sue your ass for making me think I could sit down, when really this restaurant is clogged up with a bunch of stupid skinny-ass high school girls from Alabama on the dance squad for the Thanksgiving Day Parade who ain’t even eating for crying out loud! Hell, maybe I can prove I was hit by a car while trying to cross the street and dig into my box of fries at the same time because of your negligence to provide seating or notification of its lack so I might prepare otherwise.”

And then they had to pay a couple million in damages?

Or is this just pre-emptive?
