Of all the places in a town where a HOOKER could find customers, this seems like the worst option.



20-year-old Brittany Macintyre of Nashua, New Hampshire was busted on Tuesday trying to pick up clients . . . at a public LIBRARY.



Brittany was at the library in Tewksbury, Massachusetts passing notes to guys, offering them sexual services for the reasonable price of $60.



Someone reported her to the cops . . . an undercover cop came in . . . she passed him the note offering sex for cash . . . and he arrested her.



She's been charged with sexual conduct for a fee.
