Well, both are screaming mimi's, annoying and full of shyt.
That being said, this is a rough choice.
Maggie would give you free stale coffee and pie in a heartbeat, whereas Buffy would probably suck the last dime out of you and whine about not having a tip (and remember, she can't even find money in her purse without spilling it on the table to look for it). While Maggie is very opinionated, Buffy can be caustic and downright mouthy. Maggie does have a neat and clean appearance and she seems to have her hair in place everyday, the style being dictated by the hat and uniform of du jour. Buffy's hair, not so much.
So, I'd have to choose Maggie, purely for aesthetics and that alone.

Either Roger telling you off or Elizabeth telling you off.
