how do you leave behind groceries?

ok. since i started doing the service desk, part of my responsibility has been to log and put away left behind groceries. this has, and always will, boggle my fucking mind. i understand if you are in a rush, i guess but even then, leaving behind a bag of groceries just makes no sense to me. i've had some stellar run-in's with people who were dumb enough to forget stuff.

recently, the front end manager brought up a gigantic bag of groceries. there were like, 4 frozen boxes of vegetables, some rice mixes, a bag of baby carrots, a cucumber, and some other veggie item. my eyes definitely bugged out of my head, due to the sheer size of this left behind. you have to be dumb or blind to forget something of this magnitude. so, i write it down, and just as i'm going to put the frozen stuff back on the shelf, the phone rings. i pick it up, answer accordingly, and all of a sudden i get:

"did i leave a bag of groceries?"
"was it veggies, rice, etc...?"
"YES. UGH"
"oh! it's right here i was just about to put it back on the shelf"
"WHY would you do that?"
"because...it's frozen and needs to go back on the shelf"
"ugh. whatever. its not like i'm coming back for it now anyway"
(right here i paused and thought to myself: 'then what the fuck is the big deal if i put it back on the shelf or not, crazy?')
"well, when you're ready or available to come pick it up, i wrote it down in the book, so just bring your receipt back and we'll gladly replace it for you."
"but i threw out my reciept"
"then jut say you spoke to me. my name's miss m."
"FINE. BYE"

really? i don't get it. you're the idiot who forgot a gigantic bag of groceries. not only that, i'm telling you that there's not going to be any sort of problem getting your groceries back. at all.

just another day in paradise, ladies and gentlemen.
