Rewrite of the sync api to REST.

Coworker: “hey, I know you’ve written and maintained our sync module for the past 4 years. Something I need to know? Some hints or knowledge you can share?”
Me: only thing you should not do is x and y. Otherwise you will face problems a and b.”
Coworker: “great, thanks a lot!”

2 months later...

Customer call: “da fuck are you doing? When I do stupid stuff then I face problem z and problem a!!!”

*me checking new code*

*me calling coworker*

Me: “WTF did you do? You asked for my advice and then did exactly what I told you NOT to do.”

Coworker: “oh, let me check the code..”

*coworker calls boss*

Coworker: “Boss, I can’t work with this guy, he starts fights all the time..”

*boss comes to my desk*

Boss: “I don’t want you to work on this anymore, people are complaining.”

Me: “what the fuck, I just asked him a question..”

~ 1 month later

coworker quits because he can’t handle all the bugs he caused and I have to maintain this piece of fucking retard code..
