I've managed to unintentionally and silently "pay it forward" today.
After failing to make it out of the apartment and do something constructive over at the Fountain House today (a subject more suited for the MSad/Disappoint threads), I decided to pop over to the Turkish grocer across the street to pick up a couple necessities (such as sriracha).
Since it's 1 PM on a workday, it's obviously time for the shop to be winding up for one of its many rush hours. I managed to wind my way around the other customers and picked up a few goodies, and was ready to check out.
The cashier I ended up with this time is someone I don't recognize, and I believe she might be a fairly new hire to boot (sure, just toss them to the wolves during rush hour why don't ya...), and she ended up having a little trouble with the conveyer controls, causing my purchases to violently force themselves upon the collection of the fellow in front of me.
She got a little confused with the bag of apples he'd picked out, and thought they were mine. After we both tried to clear the matter up, he apparently got his things scanned and processed, he paid, and he left.
Then it was my turn, and I thought things were working out fine until she recited the total cost of my items, which seemed a teensy bit high. I had picked out a few expensive items though, and not wanting to hold up the line and the five people behind me, I figured I'd just guessed a bad estimate and made a mental note to check the receipt when I got home.
Sure enough, the receipt revealed that I'd not only paid for the apples, but what looks like nearly the entire purchase of the dude before me. I put my shoes back on and returned to the store to make a mention of it (after psyching myself up enough to brave the potential conflict), but in the five minutes I'd been gone from the store, rush hour had settled in properly and the girl's line was now backed up into an aisle and around the shelves at the end. I didn't want to make a fuss for her, hold up the dozen or so customers waiting to get processed, or indeed stand around waiting the entire duration necessary to make it through the line.
So, instead, I just turned around and left, deciding to eat the ~$17 loss and pretend that I did a good deed, even if nobody knew about it.
I don't believe in karma, but there are times I'd really like for it to be a thing... It'd make me feel a whole lot holier when suffering through social anxiety derps.
