Its always fun to debate this, as you can equally argue both sides, and be right! LOL
There is no doubt about wasting time sifting through buckets when you are in a bind, or need to make time. Same with tools and all that, it is a huge waste of ones time when searching.
Reason I say this is that our place had this problem, some darned reason, things get out of place, buckets get full and tools scattered. I spent some time and one of the hired help did too, we found some plastic bins and similar things, had some shelving and organized it within reason, can find things much easier, use what we have or found, don't buy unless you check first, but without tipping over buckets.
I like keeping things too, and often times do use various things that have been hanging around, the part I hate is the clutter associated with it, you would be surprised at how you can condense, organize, and still keep some or all of it.
I like the old nuts and bolts, if not damaged, worn or stressed, better quality, just need to have em sorted, in bins etc. I do have one bucket from the parts room of our old dealership, heavy and a real pain to sort through.
The thing on wasting time is reality, can cost you too. Last Sept, power company drilling sub contractor provided a nice excavator for us being helpful, allowing some bow hunting for one of the guys, so here we have a machine for a weekend, no cost, just fuel. We have a water line crossing an aisle to a non freeze hydrant, problem is it freezes, and the hydrant has a leak at the connection. I'm there before 7am, hole is dug, pipe exposed before 9am you said you(dear ole dad) have the fittings, yeah ok, here's a bucket ful, sift through all that, nothing that works or fits, I have one I have one, now noon time, I need a darned 3/4 street elbow in brass for one of these hydrants, by the time I looked through a bunch of crap, went to 3 different places, I had wasted 5 hours for one lousy fitting, if that had been a paying job or machine on rental, there is the money aspect of it. I was just annoyed as its not often you have a chance to use a machine like this and the place needs a ton of work, knowing it sat there for any amount of time, when it could have been working, just not right. All started with a bucket full of the wrong parts. Finally back filled after 3 pm, should have been done way before noon.
Here's the idle machine and guys standing around it looking at a hole LOL Darned buckets full of junk, well actually was just starting to backfill, but that bucket is in the photo, should have buried that too ! Well at least it works and that line won't freeze there now.
