It's a good point. I waited for 30mins and the other guy's exit was right on clock so I assumed it was a client but who knows.
If it was her partner/receptionist then that might explain the volatile behavior, bad timing. But the sense I got was that it wasn't her first time. She lied without hesitation, shoved at will, screamed to scare. Of course all this dawned on me two days after my nerves settled lol (social anxiety indeed).
