Can I point out that not everyone with medical conditions suffer from them. I have had scoliosis since I was in my early 20s and never had more than the odd bout of sciatica. I certainly didn't warrant assistance or PIP.
30 years later, I now have a broken back (after a DA assault) and severe spinal deformities. I am now in pain every day, on morphine and every aspect of my existence is limited. I now genuinely have needs and expenses caused by my condition.
Nowadays all conditions are on Google. So it is far easier to have a condition and then take a view to get a benefit from it. I gave an example of someone I know because she genuinely has a slipped disc. However, she does not genuinely suffer every single day from it, nor the majority of days. I also felt she was listening to my woes in a 'making notes' manner, hence why I've stopped talking to her about my condition.
With a slipped disc causing enough pain to warrant getting PIP, I cannot see how you can do a "standing in the cold every night for 6 hours" type of job. It just does not add up. If she can do that in winter then what mobility restrictions can she have that requires PIP?
However, I am not her assessor. I don't know the ins and outs. I am basing my opinion on the facts given, and my own experience of back pain would never warrant doing a job like that (or construction work, which is the other thing she does)
So no, I would not report her
But yes, something seems amiss
