Customers going to a certain Japanese restaurant in Chicago may find themselves being led to their table by Groupon CEO Andrew Mason. Mason has picked up the position of a maitre d' to help him understand his customers, according to INC.

"In theory, the experience will let him better tune Groupon's activities so that both his company and his clients' businesses do well — because success for Groupon's clients means they are more likely to run more Groupon promotions, reducing the expense of acquiring new customers," said the article.

By analyzing customers, Mason has also been able to develop other ideas for his business. For example, Mason told Bloomberg Businessweek that he wants Groupon to eventually be used as the new Yellow Pages where consumers find places to eat and merchants have a form of advertising, according to INC.

Though Groupon has made news due to their Super Bowl ad and a stock price that has slid from $20 to under $10 a share, INC reports in the article, "there is evidence that Mason is learning an important lesson — and one that every entrepreneur should learn."
