Just a...

...quick thought. I saw a bakery at a shopping mall where the sign said "Take Away". Given the nature of this kind of bakery in general, isn't that kind of message a bit redundant? Makes you think if there are similar bakeries where the bread in fact not take away.

"I'll just have a loaf of bread and a couple of buns .... could I get a bag for them?"
"Sorry sir, but you are not allowed to consume our products outside the mall, if you need accessories you will have to buy them inside the store"
"But there are no places to sit even if I wanted to eat it here"
"So sorry sir, you should have read the sign. It's not our responsibility"

Alternatively, they could have a huge "Masters of the Obvious" banner there instead.
