Yeah, not buying it.
This series is good example of the character inconsistencies rife throughout the strip.
*First of all, nobody maintains that level of anger for days on end unless they're sporting some serious mental illness. (And I don't mean the cutesy OCD she supposedly has; more like full-on schizophrenia.)
*Second, how was Hannelore able to burst into the boardroom like that? Don't they have security? Wouldn't she have to sign in at the front desk or something? Wouldn't they let Beatrice know her own daughter was coming, and loaded for bear?
*Third, the idea that Hannelore could simply scream GET OUT and Beatrice would tell everyone to leave the room is laughable. More likely, she would simply tell her daughter to cool her jets, and, if Hannelore persisted, call security.
*Lastly, Beatrice is supposed to be a hardened woman who's been in corporate America for a long time. Women in corporate America face a lot of unwanted touching, as The Reckoning has taught us. Getting rudely shoved would probably be Beatrice's berzerk button; in reality, Hannelore would've gotten about half-way through the first sentence of her tirade before being interrupted by a vicious slap to the face, followed by an even-more vicious dressing-down.
But, no, we all have to listen to Hannelore's little foot-stamping screed, bleating about her tiresome mommy issues, followed by an even more tiresome "Good *day*, madam!" bit. In real life, people who pull stunts like that get tackled from behind and seriously messed up.
I don't know how this gets resolved, but I'm sure it will be a silly cliche or two, 'cuz that's how this comic rolls.
