thats hilarious. "pop" is most often used around here, but my mom is old, therefore she says "soda". we where in michigan a long time ago when i was about 12 and i remember my mom asking a safeway employee where the soda was, and he looked at us like he had no idea what we where talking about for like, 5 seconds. then he goes".....oh! you mean pop! its on isle 6."
