It's easy to pitch reserves if you know your stereotypes.
I pitched every guy wearing Abercrombie, Hollister, a wifebeater, or some sports gear a Madden/NCAA reserve.
I pitched every overweight guy with glasses who talked like he was ultra intelligent a Final Fantasy or other RPG game reserve
I pitched every guy with a Black Sabbath/Tool/other band who has black t-shirts Guitar Hero.
I asked every girl who walked in what their boyfriend/husband's favorite game was and went from there.
I had the most reserves in the store whenever I worked at GameStop.
