"Utterly rubbish signage"

Walk to the walk in centre.

See signs directing you at the car entrance

Walk in there

Get lost, several times

Have to call for directions

Consult map

See that it's actually at the other entrance and there is a sign at Street level which you don't see if you are coming from the west

Honestly you are dealing with sick people who don't have the patience to wander round for 30 mins in the dark due to signage which runs out and leaves you abandoned in a car park

Sort it out
