Just not his area...?
I might have posted this story before but here goes...
Many moons ago I was working for a body shop outsourcer and was doing second line support onsite at a customer.
Said customer decided to insource. Fair enough. The guys the new IT manager recruited were both complete assholes and didn't like the outgoing team as we were helpful to users and accessible.
Anyway, the web master, a contractor so in neither camp, was attempting to run an SQL script on a new server. He was a Microsoft guy through and through but I think the database was Postgres something similar.
Basically the script wouldn't start run.
In desperation they called me over. I had a look and could see the issue as I'd written my degree project in LAMP.
Me - Try it again and end the script with a semi colon.
Them - What!
Me - Just humour me.
Them - Ran script again, ending in a semicolon
Of course it worked.
They still hated me.
The moral of the story is that you can be quite technically competent in one area but clueless in another if you haven't been exposed to it before. The other moral is that assholes are assholes.
