PHILADELPHIA (CBS) – There seems to be a holiday for everything, and some are better than others.

For instance, did you know that Tuesday, Feb. 17th is Random Act of Kindness Day?

At restaurateur Dave Magrogan’s 16 local eateries, that means free lunch or dinner for some very lucky randomly-selected patrons.

Those lucky guests will learn they’re getting a meal for free if their bill comes to the table with the words “it’s on the house” written on it.

Magrogan-owned restaurants include five Kildare’s, four Doc Magrogan’s Oyster Houses, four Harvest Season Wine Grills and several other spots throughout the Philadelphia area.

The only thing Magrogan and his staff are asking is that the winners pay it forward.

“Keep the good karma moving and do something nice for someone else,” says Magrogan.
