In my own shop, I have lots of bins and drawers full of "junk" but it is fairly well organized.
At work, I have a little box with new plastic push rivets, hose clamps, and a good supply of new light bulbs. it takes much too long on flat rate to wait for these smalls from our slow parts department, I work flat rate.
Because of being on flat rate, I have no junk drawer. I will not waste valuable drawer space to store **** that costs me time to search for that oddball bolt, nut or washer etc. It only takes away my time to search for something that will not even get charged to the customer, and I wont get paid to search for it.
I used to have a junk drawer, but one day I spent an hour looking for something I could not find. The next day I dumped it all in the trash, and bought enough tools to fill the drawer, which now actually makes me money.
