Ok I agree that if you're following on from someone you can get a feel for what's happened before you got there. If it were a decent spark then fair enough but if you didn't know who it was then are you going to be prepared to sign an EIC? I know I wouldn't. The comment about the hidden joint was merely worst case scenario.
Yes, I've talked a bit on this thread about reputation, I don't believe that makes me a jobsworth, I don't get on a high horse about little things. If I'm following on from someone else I'm always going to make sure that my arse is covered and that everything I do is correct, I believe that that is normal course of action in many trades not just our own. I, as you appear to be, am pretty busy right now although there are some days that I refuse to work on EG I'd rather spend my Saturdays rolling around with our grandson.
When I'm on here I think that apart from the crack we are duty bound to give people the best advice we can and if that means sometimes advising guys to walk away then so be it.
I know that you weren't having a pop mate but hopefully that kind of explains my mentality
