I might be able to help here, albeit in a bitter Lefty way, because I know someone who went to school with Gideon.
I just met him, all right. It happened on a number of occasions and there was nothing I could do to avoid it. It's something that will happen again and I'm not looking forward to it. However, like death and taxes, it's unavoidable unless I see him first.
It would be unreasonable to spit in his face or punch it to a bloody pulp, however much karlos, or indeed I, might have liked me to have done, because he's a client of DH's.
DH points out that it's economically suicidal to take such fuckwits to task. He's right but we live for a better day when we can say 'fuck off, you tosser.'
Anyway, I digress. The person I know is stupid in the way that would be remedial if we spent that kind of money on state schools any more.
Luckily for him, he has a job in the City but has just enough self-awareness to have turned down a job at a more demanding bank because they would have found him out in an instant.
What's Gideon's excuse?
