I work in a restaurant in Singapore. The power of the jacket. Truth be told, if I am a guest and I get served by me, I would probably leave a bad review. I mean... Based on my rants you probably can guess that I roll eyes a lot at customers, not shy to be rude to them when they deserve it though it does not excuse me from that behaviour either. I am aware. But, since I am wearing a jacket, guests laugh it off. If I wasn't wearing a jacket I guess I would have already been fired long time ago 💀
