>Problem Patrons

>I know this post is long overdue, but we have had major staff changes. One of the full-time staff and the part-time staff left, forcing us to replace both in a fairly short amount of time. The library was in turmoil for a few months, but we should be back on track now.

The reason for this post, though thinly disguised as an update, is to ask other librarians how they deal with problem patrons.

How do you reason with a patron unwilling to listen?
