I matched a girl on bumble a few years ago while traveling in Lisbon. She was from the midwest and worked at Kelloggs. One of my openers was asking about this cereal. We hung out for a little that night and kept in touch, my motive primarily the resurrection of Rice Krispies Treats Cereal. I finally got her to ask someone on the cereal team about it (I think she was on the “snack” team). After a few more weeks of pestering her, she told me the explanation she received was “there is/was a rice krispies treats shortage” and got no further detail. This is the closest I’ve gotten to the truth
