*snicker*
you may find it weird but the "it is blue" comment is usually followed by a short describtion about content or topic. and if we have it in stock i usually find it.
i think tis a memory issue with me, the way i remember stuff. nowadays i barely see the new shipments but back when it was my duty to unpack and store the shipments i knew what every book looked like.
some customers made it a hobby coming in and asking for a special book.
i'd close my eyes, picture the book, think a bit and then say things like. in the garden section, third rack second shelf outer right corner it's yellow with a rubber boot on it...
i remember where i put things by the way they look. and i quite quickly take in surroundings and details.
my friend calls it the most useless superpower, cause my flat seems to be made of kryptonite for i never can find my car keys, glasses, cell phone, wallett...(the keys to my motorbike are always in the right pocket of my leather jacket cause if i put them else where i have to search for a week)
perhaps tis cause you're more alert when outside of the safety of your own flat. it works great in other peoples homes. i come in and usually take a close look arround, tis a habit. (i'm not raiding the flat, i just sit down and look around the room whilst talking...) my best friend called me up several times saying things like "you were here yesterday did you see the keys/dvd/book/whatever and when i know how the object looks, like remembering the cover of the book or dvd, i remember where i saw it last. sometimes it pisses her off, she bought a jigsaw a few years back in the store where i work and i knew the picture cause, obviously, i had sold it a dozen times. a year later she finally started the puzzle and told me that there was this weird shaped piece with a fried egg on it and she had no idea where in the very detailed picture it belonged.
my comment was "left lower corner just beneath the horses hind legs."
2 days later she phoned me "i hate you" i was right on spot with the jigsaw piece

:D
sadly i have no photographic memory, having that would be cool, i more or less have a pile of paper memory mostly remembering the most useless things. dates and appointments are lost with me when you want to meet with me you have to tell me date and time twice at least and never do things like "let's meet on the third" and then tell me "see you thursday" cause i would never compare the name of the day to the actual date. i usually remember my birthday because when leaving my flat i usually step onto a present on the way out. my art deco wine glasses were saved only because the light reflected in them and i saw them before i stepped out...
but to come full circle
when you come to the store and tell me you're looking for a blue book and you faintly remember it was a murder novel and the inspector was a woman in madrid, i would start picturing the book in my head, sometimes clearly enough so i can read the title. if i read the book i could possibly tell you a bit of the content to veryfy if it's the right one. and then i would direct you to the shelf or fire up the computer to order it
my boss usually keeps me busy cause when i get bored at work i tend to do stupid things like sorting the dvds by colour.... (been there, done that)
yesterday i sorted cds.... they were just piled into the racks and i sorted them by genre after my boss dismissed the idea of sortimg them by total playing time, or most stupid looking fellow on cover
i admitt it would be difficult to explain that system to a custommer....
