Yes, when i feel dissatisfied, I complain. I wish someone would hire me for this.  Companies, organizations, whatever that need to upgrade their services, please hire me. I would surely find a hole to be complained about.   Am i annoying for others? I guess yes. If you cannot accept any mistakes made by you to be complained, then i would be a horrible person for you. On the other hand, my advice might be something good for your companies. I always feel happy whenever someone sends the link for customer satisfaction. I would surely write long comments for them. Of course, rarely I would receive follow up from their side. Hahaha. I complain about everything but these days i have minimized complaining about food since there is barakah in it. A nd yes, I am available to be hired as a ghost customer, a ghost buyer, anything - you name it.
