So. Say Becca gets her coffee/tea/bakery shop she's wanting. She wouldn't want to work alone, y'know? She would quite possibly beg her dear, sweet, utterly wonderful roommate to work with her. Thing is? Her "dear, sweet, utterly wonderful" roommate happens to be Priss, who would maul anyone who described her that way, and who wasn't Becca. "Fucking evil ice bitch" is a far better description, really. Buuut, she'd probably agree eventually, especially if she was bored and didn't have many jobs coming in (she's a freelance bounty hunter/assassin/what have you). She'd hate everything about it: the bright cheery atmosphere, the customers, and especially having to wear pastel. Because Becca likes happy colors, so that'd be the uniform. Khaki pants/capris and a polo in a light green, probably. Possibly with white stripes. And she'd have to pretend to be a generally friendly person, which would suck a whole lot of ass, and which she would only agree to to please Becca, and possibly for the promise of some nookie or something after work. Not that that's what Becca would call it, of course.
I think once things got going they'd have the best behaved customers ever, cuz they would sorta ph34r the evil waitress. Mwaha. They'll keep coming back for the delicious drinks and munchies, dammit. And who knows, maybe (shock and horror!) there might be a few customers Priss could make friends with because they're tolerable. She doesn't actually have any friends outside of their tight little circle, really. Not that she cares of course, it's just a funny thought.
What's even funnier, is the idea of Miss Semi-Evil Incarnate Priss going around being friendly and wearing happy pastels while serving people tea and biscuits. Heehee.
