Oh, how pleasant.

A library full of sweaty patrons.

Lots of patrons get insulted when offered a large print book. 

(Even if the regular print is out.  It's bizarre.  I guess it's somewhat similar to being insulted by NOT getting carding when buying alcohol.  Or something.)

Anyway, if they get huffy, I tell them that lots of people like to bring large print books to the gym with them.  It never fails, because then THEY THINK that I THINK that they go to the gym regularly and they love me again.
