When I was 17 I used to work in a supermarket on the checkouts. Occasionally an item wouldn’t scan properly and it would need to be rescanned.
I decided any customers that I liked, that greeted me warmly or were a hot girl, would not get their items rescanned. That I would pretend not to notice, effectively giving the item to them for free.
With so many beeps going off in front and behind you I quickly learned that the way not to get caught was to pretend not to notice miss-scanned items. The store security looking out for dodgy behavior from checkout operators couldn’t distinguish the beeps (or lack of) and would rely on reading the people and looking for nervous behavior.
I recall one girl in particular; she had a warm smile and was pleasantly engaging. I liked her immediately. For some reason an unusually high number of items were not scanning correctly.
And she noticed.
When she noticed, she looked me directly in the eyes; I could read the question on her face but waited to see if she would say anything.
She knew I was doing it on purpose.
I knew that she knew.
Neither of us said a word.
I’m no different from everyone else; there are people everywhere in positions with some responsibility making whimsical decisions simply based on how they feel about you.
Do you take the time to smile and say hello? You may get some free groceries.
