When a man is looking for an item generally in an uncrowded space and he quickly glances over the space then declares that he can't find it then calls for a female to locate said item. She then looks behind something and finds said item in plain sight.
John was looking for his phone and on the counter was a candle a cup and Johns phone. John does a man scan and states he can't find it then calls for his wife who finds his phone behind the cup.
The constant checking on the refridgerator for food even though you know there is none in there; usually occurs every 2-5 minutes for a person not smoking pot. For pot smokers, it occurs about every minute followed by vacant stares.
Normal person: Bro, I've pulled about 5 fridge scans and still nothing...lets check the pantry!
Pot smoker: Broooo, I've fridge scanned like 5 times in 5 minutes and still nothing. (followed by the vacant stares)
Scanning fine art at work is completely normal. I am currently scanning fine art as I write this. My favourite place to scan fine art is in public places such as movie theatres and playgrounds.
