Libraries offer an incredible array of goods and services these days.
Yet almost daily someone will come in or call and ask for something we don't have, can't offer, wouldn't remotely be able to offer even with all the budget money in the world.
Customer response to their requests being unfullfilled is usually a very reasonable "Oh, okay, thanks."
Some days, the customer will get quite rowdy and upset that he/she can't have what they want. They don't want a referral to a place where they could get it. No explanation will satisy the fact that they just want it NOW. And the library is the one they want it from.
