Plus, as an added attraction, every El Jevi kiosko is required by the boss, El Jevi himself, to always play heavy metal, or at least, classic rock, music. (this is true. I have asked. And El Jevi is real- a Ukranian/Argentine self made man who built the chain from a single location on Billinghurst 20 year ago)
That said, the quality of the machines at a real copy center is much better, so it depends what you are printing. I use several real copy shops that can print in full color, or large sizes, or do binding, or collating, or make stickers or magnets, all of which, at one time or another, I have needed. But for a few B&W, El Jevi or many other small kioskos are just fine.
