The Greatest of All.
[New York Letter in Boston Herald.]
Mercy, how those fellows ate, how peremptory they were in order, how eager in contemplation, how earnest in cutting up, how vigorous in putting down. they hurried through the operation as though they were having a tooth pulled, and the quicker it was over the better. I was particularly struck by one man who finished a pork pie, a cup of custard, some cold coffee and fifteen or twenty pieces of cheese in less time, I was going to say, than it takes me to tell it, who asked, while the tumbler was still resting in his mouth and the milk was gurgling down his throat, “Check, please,” and, stretching out the other hand for the ticket as he moved away, pressing his fingers into his side-pocket for change with which to pay.

Summary:
That’s because when the check arrives, there’ll be condoms instead. Cabbage and Condoms, a Thai restaurant overseen by the Bangkok-based Population and Development Association, serves both items. The eatery plans to open its first overseas outlet in Beijing next month. “We have been working with Chinese family-planning groups and chose Beijing because it is the capital of the world’s most populous country,” says PDA founding chairman Mechai Viravaidya, who is widely known as “Mr. Condom” for his promotion of the device to stem population growth and the spread of sexually transmitted diseases.

21 March 2015, Saint Paul Pioneer Press (St. Paul, MN), “St. Paul’s National Checking looks beyond the iconic green and white slip” by Nick Woltman, pg. >:
When you holler, “Check, please!” at a roadside diner in the United States, you’ll probably be handed a green and white slip with your order scribbled on it.
 
Chances are that slip was printed in St. Paul by National Checking Co.
 
Headquartered on a bluff overlooking the Mississippi River, 110-year-old National Checking sells more restaurant order pads than any other company.
 
“We have a significant market share,” said Ben Olk III, the company’s second-generation president. “The problem is that it’s a declining product.”
Restaurants are increasingly eschewing the traditional guest check in favor of thermal-printed register rolls.
