This practice is so commonplace and widespread that I don't see what good it does discussing whether people should do it. People are doing it - all the time and in every counter service restaurant. As far as I know, there's no rule or policy against it. The question is what, if anything, can or should be done about it, and that falls squarely on Disney. We go during less busy times when it is not so difficult to find a table (we don't go to the most popular restaurants, though). Disney isn't going to do something to fix a problem that doesn't exist. When it is busy, or for perpetually busy restaurants, Disney can stop people from going to a table until after they've ordered. As far as I can tell, the only problem is that they don't implement this policy as often as it's needed. If there are several people circling with food and no table, then it's a problem and it should be addressed. If enough people contact Disney and complain about it, maybe they will start implementing the no-food, no-table solution more readily.
