Whenever I do things I always consider, how can do it conveniently. It's annoying to do the tasks and yet there will be mess left behind. Obviously, it sounds more tasks to do.
Just like when you bake in your own kitchen and you choose to left trays and moulds unclean. Or when you shave and you didn't use the shaving stand for your shaving brush.
At work, preparing paper tablets in the pharmacy will be a lot easier when all your tools are kept clean after every use. Imagine if your mortar and pestle are kept with residue of the previous medicines you prepared. Not only it's gross but also it will contaminate the next thing you will prepare.
Keeping a tidy and neat pharmacy allows us to do our jobs more conveniently and efficiently. The risks of dispensing wrong drugs will be eliminated and every nice things will follow.
