I don't think you need a temporary license if you are not selling it. When I opened my Pizza Pub we didn't have the liquor license yet so we gave it away for free. It was great advertising too.
Last time I was in Cincy, Crosley Field was the baseball stadium, one of my favs of all time...
I was wanting to hold an event on my store. I do not have a liquor license, but I would not charge for the event.
It's a cake walk for future brides. Is this illegal if you are not charging for anything? I imagine it, but input appreciated.
