What would you do?
I'm an avid reader, mostly mystery novels. So I joined a mystery book club that meets once a week at Barnes and Noble.
After the meeting I was walking up to the checkout and I noticed the other club members did not come with me. They went directly out the front door with their books. (I forgot to mention everyone brings a book bag with notes, other books, personal stuff, etc.) I was absolutely the only one who stopped and paid. Second meeting I watched carefully. Some took more than just the current book, but no one went to checkout.
I thought maybe the best thing would be to just write a note to B&N and ask if there is an agreement about book clubers paying later/credits/whatever. If no agreement, maybe they better start doing a bag search. Without a doubt this will get the club thrown out of B&N but I haven't gone back anyway.
