I've got a GREAT one for this - so a couple months back I was in a Lawson's and needed to print a few pages off my USB for work. I was running a bit late and in a hurry but there was a guy using the copier. If you're familiar with Hans Moleman from the Simpsons this guy was basically his Japanese twin - probably in his 60's, thick glasses, short and slouched over, pretty shabbily dressed. He's making big A3 size color copies on the machine and has a huge bag full of magazines at his feet. They've all got post-it notes with cartoon cats on them showing the pages he's planning on copying. There are a LOT of magazines. I notice he has about 1700 yen loaded in the machine so he was going to be there for a while.
What kind of magazines, you ask? Train time schedules? Baseball scores? Results from the horse track?
SUPER hardcore porn - the kind I didn't think they even made as print magazines anymore. He's swapping the magazines in and out and its just a parade of wide-open orifices and penetration.
Picked up a few things I needed from the shop, paid for them and looped back around - of course he was nowhere near finished. Asked him if he'd mind if I cut in and just used the machine for a few seconds... He very assertively said "No, I was here first. You have to wait."
Dude was dedicated. I, for one, opted to just go to FamilyMart.
