When I started my current job I fucked up my first deploy ever so slightly but In the end managed to get it going with a quick hack (unpacking our war file modifying some properties and a jsp page before restarting the tomcat server )

One of the senior developers was having a really bad day and decided I was who he was going to take it out on, calling me a cowboy (in the Uk that’s a bad thing) blah blah, being really nasty and condescending to me.

I was about ready to shout at him as it was his dodgy configuration that caused the issue in the first place, but instead I took a deep breath and firmly (but calmly) told him never to speak to me like that again or we would have a problem.

5 years later he’s never spoken to me like that again and is actually a pretty decent guy.

Moral of the story people have bad days but also don’t let people take the piss.
