Hmmm
I think a lot of receptionists can be very motherly as it kind of goes with the territory, as they need to know where everyone is at all times. You say she is a secretary so maybe my perception of what she does (or at least is supposed to be doing) is off.
Our receptionist calls me hon all the time. I know it's not the same but she's not the first receptionist to have done that and probably won't be the last.
Anyway, an employee not doing work, or screwing up, or palming it off on other people, is something that can be documented. And it is something that can reflect on her boss. After all, if other workers are disgruntled, or are unable to do their jobs because she isn't doing hers (and they're doing hers), or are cleaning up after her mistakes for the umpteenth time, then that will reflect poorly on the boss.
You have friends there who also have a problem with her, yes? Then it's time to start getting stuff in writing, because verbiage and subtlety ain't cuttin' it. Just something like

Doing Edie's job: .5 hrs
[u]Tuesday, March 21, 2006[/u]

etc etc throughout the week, ending with
[u][b]Recap for week of March 20 - 24, 2006[/b][/u]
Doing my job: 30.5 hrs
Lunches: 5.5 hrs
Doing Edie's job or fixing her mistakes: 9.0 hrs
Pile up enough of those and any supervisor will have to take notice.
