Also last year some dealer sold hentai products 
to an underage customer, and the parent totally 
freaked out (justified, true).  Since it was at 
Disney's hotel, they called in the cops and 
anything even remotely objectionable was pulled 
instantly - it was really pretty bad. They closed 
the dealer room down for over 2 hours while the 
cops went through the dealers booths. :P  
Unfortunately I hadn't done any buying of 
doujinshi and there were NONE to be found after - 
they even pulled the "normal" (ie: gag and 
serious storyline) that I was after. -_-;  All 
because of one kid and a REALLY stupid dealer. :p
