Failing a Pink slip

[qwertyu1234567]

Hi Guys,
Fancy popping my cherry on this :

Took my car for a Pink slip inspection today and the bloke tells
me that both my light's are discoloured and need replacing. :
What a crock of ......
I've had the car for near on, 7 years, and they are
the same 2day as they were back then and not a worry.

Anyways, Question is, after getting a White Slip, do you have to
go back to the same place to get a Pink Slip or can I go to
another fellow down the road 2morrow without spending a heap
fixing something that don't need fixing : ,
and get a Pinky from him ?

Cheers Guys, Q.
