Dear Teen Girl:
Yes, I am aware that in the children's department, they do give you a free guest pass after time on your library card has run out if you need to do homework. That's why you use the computers in the children's and youth services department: they will give you two more hours free.
We are the adult services department, however, and we charge for the guest pass unless you have a reallllllllly convincing sob story, or the computer cut you off in mid job application, and you are, at minimum, gracious about asking for a free guest pass.
Mumbling the request into your shirt with your head turned away from me, then rolling your eyes, sighing and snapping the words out One. At. A. Time, "Gimme. A. Free. Guest. Pass" following up with blowing a bubble of gum and then popping it in my face gets you my most sympathetic smile and the following "I am sorry, but in the adult department we do not give out free guest passes. These are the rules by which me must abide. Please check with the children's or teen department for a computer."
You really do not want to know what I am thinking.
