Its just habit, I suppose it came about night fishing for sea trout, everything always in the same pocket or compartment of my fishing bag and before that long distance walking and expeditions, the last thing you wanted to do was empty your rucksack to find something when it was p*ssing down.
Anyhow, this company we’ve been taken over by is well into “New 5S” or Sort, Standardize, Straighten, Shine, Sustain and the new bit of the 5S is Spirit. We even have to put little labels on all our cupboards and desk drawers saying what’s in them. So keeping my fishing gear tidy, no problem.
