If you give away pizza for free for 3 months, and then stop, even if you announced ahead of time that you'd do that, people will still be upset when they show up for their free pizza after that 3 months. If you give away free pizza for a week, it won't be a big deal. After a certain amount of time, people expect it and will be quite upset when it ends, no matter how you try to prepare them. Of course, others are more reasonable. But there are far too many who will simply expect it forever.
