It depends on the company, on the country and the manager. I sometimes organize dinners for my team (it's France after all). People can freely come or not and there is always someone who does not come. This someone changes all the time and nobody is keeping count. I know my team inside out and, believe me, they will say when something pisses them off. Clearly. The dinners are not one of these things.
