Question

Why do you have to use a library computer for a limited time only?

Answer 1

if you are the only member of the library use it all the time, have you ever turned around and seen the queue behind you??

Answer 2

Because it allows other members equal opportunities to use them. This is a fair system.  

Answer 3

Cause it's free? And other people want to use it, but there is not enough for everyone??

At my library they have free wifi :D

Answer 4

Because you are not the only person who will use the computer. If you don't want to have a limited time, buy your own computer.

good luck!
