Think of it like eating out. MS/Sony shops are restaurants, you go in, see the menu, order, eat, done. Maybe a little extra for dessert or a tip for the waiter, just your classic dinner.
Appstores are the “all you can eat” festival tickets. Free tastings, small snacks, nice music, but if you get really hungry, then a sudden hot dog costs 4 euros, a coke 5 euros, toilets cost 1 euro (with a queue of 20 people) and every 5 meters someone is hard at work trying to help you, get him to have a drink in his shop, the 1st for free of course, the 2nd for 10 euros or more.
Completely different principles, completely different rules and mentality. It just happens regularly that companies try the ‘shortcuts’, mixing beer with water, ‘freshly made’ it comes from the microwave, and when they try the other side too… then 1 example is enough and immediately another 100 to try it too you . But as long as it meets the rules, regulations and sanitary laws, silly but then it’s fine. Then it is only the visitor who can make a difference there… and that is precisely the problem
