Uh. Only a few days back I told the cashier at a dessert café that I don't need printed receipts and she gave me a confused look and printed anyway. Plus I understand that some terminals processing card payment prints receipts as soon as the transaction is approved.. Sadly.
Kudos to automated machines that allow e-receipts! However for supermarkets, in my country this is only available in a more high-end supermarket, which in the long run may not be very sustainable for my wallet heh.. I hope that more outlets will have this paperless option. Besides going towards less waste it is just annoying to juggle with so many things on hands and piling up papers in the wallet or bag. And oh if something is wet this paper will tear and parts of it will stick on your belongings. Sad.
Nonetheless I am also thinking about places that print queue numbers. I won't go as far as banks. Bubble tea/boba stalls here do that! Probably they want to avoid customers taking the wrong item, but I think we shall find another way to do so. Names, perhaps, like how an infamous coffee chain (that I don't drink from btw hah) does it. Or.. Idk. Suggestions?
