When Faith Patterson leaves the backroom at work to deal with yet another customer that won't stop hitting the "ring for service" bell, she expects to see another upset parent that doesn't care how understaffed the library is.

When Lex holds up a mini dry-erase board with a simple message on it, Faith has to quickly decide which course of action to take... after she stops panicking, that is.
