Sitting in the Gypsy Moth pub - like you do - before seeing the ships, I noticed the registration plate of the ambulance parked outside:
Company Name - First Aid Cover Ltd
Registration - P999 FAC
The car is - V999 FAC
This one is - M999 FAC
Apparently, when the company was started the owner bought up all these 999 plates for his vehicles.
Being the "Boss", his plate is B999 FAC we were told.
