I do very little 1st fix in the way that most of you do, the nearest I get is normally sticky back trunking and surface boxes most of the time, and no more than 6 points per job TBH.
The rest of what I do is I&T, fault finding & repair, but, a LOT of it is stupid risk in comparison to domestic.
Last Monday about 500k's worth of machine, then another over £100k.
Tuesday a cheap one circa £30k, then another of about the same value, then another the same.
Wed, a cheap one only about £12k
Thursday, playing with bits off a £30k machine which needs to be running by Wednesday, else client will be in trouble, and IF I mucked it up replacements are circa 16 weeks away.
Friday, a really cheap day only playing with bits of about £3k.
