I used to work with a woman who would do the reflexive pronoun thing whenever she got hoity toity with someone on the phone.
We once had to endure a full five minute, full volume diatribe……
“Well, we sent an invoice to yourselves. What do you mean you haven’t received it? We need payment by yourselves to ourselves by the end of the week.”
On and on and on, thinking she was sounding clever. I’ll wager the other firm had her on speaker and were winding her up deliberately and pissing themselves at how **** stupid she was sounding.
**** idiot!
