Just to be an awkward git, one of the best but also the worst jobs I've had was working for BT as the emergency operator - you know, the goon that answers with "Emergency, which service?" when you dial 999 or 112.
Genuinely loved that job, but it paid an absolute pittance. It was both fast paced ad fulfilling, but some of the shit that you hear still rattles my cage even today. Most of the calls were a blur while the job was getting done well, but some of them made you feel pure helpless slow-motion despair while you tried every trick in the book to fast track a particularly horrible call to the appropriate service.
I'm glad I did it but I absolutely wasn't ready for the emotional devastation that it caused, and still caus es.
10/10 would do again A+++++
