How you pronounce things differs depending upon where you're from.
See, I exlpained to Matt how people in ENgland (some people, anyway) pronounce TERRITORY ''Tair-ih-tree" rather than the way Americans pronounce it: ''Tair-ih-tor-ree.'' So yes, word pronunciation definately depend on where you've grown up and where your speech skills have developed.
EDIT: And it's not just Cece and to of her friends that pronounce it like that. It's anyone that lives in or around Cece's nighborhood, including the bakery people. :\
