These pushy, grabby, shabbily dressed middle-aged women (never get between a herd of librarians and (a) free swag or (b) the shuttle bus) are my peers and colleagues?

Cruel, but fair. And they don't even know why they do it! AALL is always followed by several days of returnees trying to get people to take all the promotional crap they hauled back with them off their hands. I have like half a dozen sippy cups with vendor logos on and around my desk.
