I think you should sue.
Sure, you won’t get much money. Heck, odds are you won’t get any at all. But the lawyers can start a class-action suit. THEY'LL make money.
Just think. The restaurant will fold. A bunch of people will be unemployed. The proprietor’s dreams will be crushed. The owner’s insurance will have to pay out big bucks. All the lawyers will all get new Caymens, and you'll get $150!
Woo Ho! It’s good to make the laws!
