A fucking overenthusiastic twat wanted to check my badge when I entered the customer premises. He even interrupted his discussion with another person. Also, he complained that the badge should be hanging around my neck (as the instructions say!) because I happened to have it in my hand after having entered the premises through a locked door that requires me to use the badge to unlock it.
Seriously, this is how we treat grown-up people? No wonder this world is such a shitty place to live in if one cannot trust another person to use their common sense. Fucking annoying.
