why do you have to use their computers anyway? i know from extensive internet cafe outings that using a communal computer is usually a HUGE waste of your time, compared with using your own, if it is at all possible to do so. I always feel a dread ana paranoia about going to use those internet cafes these days as i feel that once you have paid for your hour, you might find that you have been loocked out from doing all the things you were trying to do. then you wasted you r time and your money.
the last one i was in, they had a really fast internet connection, but the computers were really slow! i had never before worked on a computer which was noticably slower than the internet connection it was attached to! you could tell it had loaded webpagesquickly, for example, but was just struggling to draw the screen up to speed!
