Sensor cleaning in Newcastle upon Tyne
Same day? I'd expect it to be done while I wait. It's not a difficult or time consuming task.
....or the sort of job you'd have a big queue for? you can have keys cut, shoes repaired, and watch batteries changed while you wait, and every one of those is likely to take just as long yet also have people queuing.
Truth is they probably dont want you to see how easy it is so you'll come back time and again, and who can blame them really

My Names Alan, and I'm a lensaholic.

Get the tools and do it yourself, just be careful.
