I weep for our school system

Cust: Do you have a photocopier?
Me: Not really no. Why?
Cust: I want to photocopy this book so I don't have to buy it.
Me: What? You want me to photocopy the book?
Cust: Well not the whole book, just most of it.
Me: Ummm, you know that's not okay right?
Cust: Oh no, it's fine. I'm a teacher. I can photocopy anything.

After standing with my mouth agape for a moment.... (and I'll admit maybe not one of my best days)

Me: I'm pretty sure you're only allowed to copy up to 10% out of any particular book for classroom use. However, that's not really the point. Asking me to photocopy it here, in the store, so you don't have to buy it? Wow. Now would you like me to ring that up for you or are you finished here?
