Fucked up job

Why do I have such a fucking job? I hate my job. It covers the seas and the mountains or what Hokkien people would call "pau suah pau hai". I get so many complains on deliveries, quality issues, sampling issues, pricing issues, raw material issues, lead time issues, customers claims and even shit and toilet issues. No pun intended. Yes, literally shit issues. One customer messed up the toilet with shit on the floor and didn't even bother to flush the toilet after finishing his business... it then becomes my issue. Why? Cos that asshole is my customer. Fuck! Can't believe a well travelled businessman can do such a thing.
