FAQ:
Q: I dont have a printer at home!
A: An office store or library has it.
Q: But will they let me print copyrighted shit?
A: If the printers are self serve, they dont know. Unless its something absolutely socially unacceptable, nobody is going to glance over your shoulder and then rush over to stop you. Even if the printers are not self serve, I’ve never dealt with a business who cares.
