Or company get togethers and corporate events. Get fucked with your group activities, "team building" games, pointless unfunny speeches from the management and other similar nonsense. If you want your employees to bond for one evening then free food and drinks is more than enough. And even then, honestly, nobody wants to spend (or rather waste) their free time with people they spend at least 8 hours a day, 5 days a week in the office.
