@matigo Also, this afternoon, when I had to be elsewhere, he was looking after me on the chat because he wanted to demo the app in some meeting I had no idea about. He wanted to use the latest and greatest app version that also requires a breaking server change to work. I did tell him that earlier today, but he was too hasty to install the latest version and wanted to use it. So, they updated the server and something broke, so obviously I got all the blame for it. Well, I was elsewhere and couldn't respond in any way, so he had to revert back to an old version (both the app and the server). That caused him to be quite a jerk once again. This time I gave something back, saying that "I'm sorry that I have a life outside this work". I do hope that was aggressive enough.
