When one steps into a disorganised situation (or one for which one does not know the organisation, or even both), one has to put some order into the situation. If order has been ignored for some time, it can take a lot of time to clean up the mess.
Consider a warehouse where stock is not stored in an orderly fashion. It can take a lot longer than it should to find things, and sometimes, things can be missed. One might be overstocked on items, because they are in multiple places.
If one takes the time to organise an area for easy accessibility, it can be very easy to find things or know that there are none.
But this organisation takes time, and it can seem that not “wasting time” is efficient. Actually, it pays for itself in the long run.
Saving yourself a bit of trouble now may give you way more trouble later. Alternatively, spending a bit of time now can buy you valuable time later.
