It’s not often you see a small child in this restaurant. Could it be that, until two months ago, this was one of the most popular places in town where you could have a burger and a beer AND a cigarette (or ten)? Many conscientious parents do not want their children exposed to second-hand smoke.
It could also be this pseudo-warning to parents on the front of the menu: control your kids or else they could get hurt. I think the management of this establishment doesn’t want kids out of their chairs and hanging around the pool tables because it could cause one of the patrons to miss an important shot or, potentially, tripping a server with a tray full of beer. Yes, that must be it.
This “warning” on the menu is a disaster, from a grammar and spelling perspective. They’ve capitalized every word, perhaps for emphasis. They’ve used a sentence fragment, also ostensibly for emphasis. A sentence fragment, generally, is a sentence which lacks both a subject and a verb. The replacement of the period with a comma after “please” could solve this problem. Then there’s the omission of the “s” in “minor”.
This restaurant is a great place for awesome junk food, but as far as setting a good example for your kids when it comes to the English language, it could use some help. I also wonder, now that the statewide smoking ban in restaurants is in effect, whether this restaurant will be more welcoming to families with kids?
