At the car
A repair in Southwark that cannot wait.
Southwark is full of people whose day cannot slip. Nurses due at Guy's Hospital behind London Bridge or the Maudsley at Denmark Hill, traders with a Borough Market pitch, parents with the Camberwell school run along Camberwell New Road, couriers working out of Bermondsey arches. The tyre has a screw in it, it is still mostly inflated, and everything hinges on it being fixed before the car has to leave. That is an urgent repair, not a booking for later in the week.
Ring 07473 720871, say when the car must leave and where it is: the Guy's car park, a Denmark Hill permit bay, the Camberwell estate. Whether the day has space is said plainly, with an honest arrival agreed. At the car the tyre comes off, a hole in the central band up to 6 mm is sealed from the inside as BS AU 159 requires; balance, refit, done. If a patch will not do, you are offered a replacement, priced there in the car park.
