These people are sick so this is not surprising.
I get products from an industrial company and each shipment comes with a little Christian pamphlet. Another company’s electronics catalog always comes with a Bible quote on the inside front cover. Not displayed in a prominent way, it’s just there along with the usual stuff about new products and the catalog index.
Maybe vendors of cakes, rings and the like should include something like a Bible verse or the like with their quotes and receipts.
