With some jobs, we know the risks. Police officer, soldier, firefighter – the dangers to life are unpalatable, but at least we know them before we take up our work.

Paramedics will only attend calls in certain precincts of many large cities if supported by security. But working as an attendant in a garage really should not present worries to employees.
