Let's make a list, I'll start...........
1. Shaking hands.
I'm not a germaphobe, but I've just met you - why the f___ would I want to touch your hand????
These make absolutely no frigging sense and serve no purpose. In a place like Australia that is insanely hot, they are just asinine
.......to have an open collar and/or have your shirt buttons showing is a faux pas, but having something sealing in the heat and having sweat marks all over you is OK? I see.
