Differential diagnosis

Reasons to use an ambulance...

Pity it doesn't distinguish between chest pain that originates from a pulled muscle, a cracked rib, indigestion, angina or myocardial infarction. Pity most folks wouldn't know how to define "serious blood loss"...

Isn't that what the paramedics are for?

(Spotted while we were getting petrol on the way home. The ambulance was parked in a Tesco garage while the driver went in to the shop to pick up her lunch).
