Mario Bros. Grocery is a grocery store owned by Mario and Luigi in Super Mario Bros.: Peach-hime Kyushutsu Dai Sakusen!. Although they're plumbers in every other portrayal, there's no mention of any plumbing at all in the anime. It is a store they run together where they sell foods and useful items to people who shop there. This is what they do in this movie rather than how they are portrayed everywhere else as plumbers. During the movie Luigi and Mario are seen helping an old lady get her groceries however, Mario is to distracted by his thoughts of Princess Peach and just grabs her a bunch of random items causing the old lady to yell at him. After the movie is over, Bowser and a couple of Koopa Troopas are shown working there happily with Mario and Luigi,
