Library card registration, check ins and check outs and:
A lovely elderly English grand dame who's a regular patron needs help with the copy card machine and then the copier.
A gentleman checking out "The Crucible" recognizes me as SC's mom. I didn't recognize him as the dad of one of her sometimes friends, though we've met once before.
Ewww-a patron has reserved Michelle Malkin's rag of a book. It has a shortened loan period because there are a number of reserves on it--11. Not in the realm of Dan Brown's latest--there are 204 reserves on that great work of literature. 
More tripe--our Local History Department manager is bewildered by why we have a copy of Tori Spelling's magnum opus. We have it for the same reason as we have books by other deep minds like Kathie Lee Gifford--people actually read the stuff 

A mom is renewing a board book for the 3rd time. Tell her if the kid wants the book for 9 weeks straight, she should probably buy it--it's proved itself a keeper.
A lady wants to buy 3 books from the book sale but doesn't have cash with her. I tell her to pay us next time--it's only two dollars.
No, we don't have study rooms you can reserve. The only closed room we have is my story room and it's not up for use by the general public.
I don't have to renew that CD for you--it's apparently already been renewed for you by your husband.
You can have it until mid-October and then renew it one more time. Understandable--19 discs IS a lot to listen to!
And last but not least:
Yes, we sell books at our book sale--there's stuff on the trucks right now.
And we happily take donations and sell them.
But no, we don't BUY books from patrons!
