Ok, not everyone in the world, but every time we make an appointment with someone like a plumber, IT technician, BT person, joiner, electrician etc they are always late or don't turn up or don't return calls/emails. It's just shit and unprofessional and has been happening ever since we moved two years ago.
I welcome tales of people not being shit by the way, it will reassure me that it's just bad luck.
