It crossed my mind to give it a go because the guy was pressuring me to but thought the better of it.
The thing is that if you start to play the hero and try and fix problems like these then the guy who is responsible for it can claim that you've made them worse and I don't think it is fair to put the customer in that position when he is the injured party and entitled to the problem being taken care if the cc'er, who shouldn't have made such a basic mistake in the first place.
As ever, when something goes tits up it is always for the fussiest customer you ever came across and hence my not wanting to get involved.
We always put sticky tabs under every piece of furniture, wood or metal, whether it is being moved or not, and protective strips along the front if any static cabinets etc. some may think it OTT, but it looks professional and heads off any nightmare our friend is now going through.
