Free pancakes at IHOP question…..

Is anybody else getting the free pancakes? I'm curious for those of you who do, do you also leave a tip/donate? I'd really like to quickly go in and get some pancakes and leave but I feel like I'll be giving a dirty look lol
I don't mind leaving a small donation or a tip but I don't want to do both, that defeats the purpose, lol.
Thanks………………………………………………,
