i went to a random gamestop in a mall once just to browse and maybe find a good deal. the clerk there said hi,asked what kind of games i play, then kept following me and asking me why i only have a wii (i made the mistake of telling him). he then proceeded to try very very hard to get me to buy a PS3 specifically. when i said no for the tenth time very sternly, he got all offended and then mumbled and then began to complain about how MH3, madworld, and Tatsunoko vs. Capcom were on the wii. finally i got tired of it and left. he yelled something inaudible at me as i left.
that is the only time iv ever had trouble at a gamestop.
