Groupon Inc (NASDAQ:GRPN) CEO, Andrew Mason, has just unleashed a Twitter rant about mayonnaise. That’s right. Mayonnaise. After almost losing his job late last year, Mason has mostly kept his head down lately—after since threatening to fire himself in November. But of all the things to rant about. Mayonnaise?


He warns his Twitter followers up front that he’s about to do his first “multipart Twitter rant.” He even said he realized that he might regret the rant. His main complaint was about sandwich shops which “put mayonnaise on all or most of their sandwiches by default.”

He said it doesn’t make any sense because it makes the bread soggy, even for those who actually like mayonnaise. So he gives a bit of business advice to sandwich shop owners. He says they should put it on the side to attract more customers while keeping their old customers.

Now there are plenty of other things Groupon Inc (NASDAQ:GRPN)’s CEO might want to rant about. He might be in a good mood today because his company’s stock jumped 5 percent after analysts at Sterne Agee upgraded it. However, the stock has still fallen more than 75 percent since the company’s initial public offering in 2011, so there’s plenty to rant about there.

Forbes also reminds us about the class-action lawsuits Groupon Inc (NASDAQ:GRPN) faces and the continual shakeups that are going on in the company’s sales department. But it’s none of these issues that have Mason all hot and bothered.

It’s mayonnaise.

Well it’s good to be passionate about something, even if it’s only your sandwiches.
