Yes but the details of the job were important and hence you remember more of it. If i don't put my keys in the same place, it takes me ages to find them because I can't remember where i put them.
You need to mentally acknowledge your actions and surroundings eg when you put your keys down, remember where you are/surroundings etc. This helps plant the memory. Problen is, if I did that I'd just put the keys back in their regular place!
When your brain is processing lots of info, it will sometimes discard what it thinks is unnecessary despite the fact that you may think it's unimportant. Hence the more you do strengthen the memory of something, the more likely it is to remain.
