“But they taste so good”: Supermarket urges customers to refrain from disgusting practices. “What idiot puts those things in their mouth?? Bah!” says another user indignantly and adds: “Always stick it in my nose, it’s more practical.” “Do the deposit voucher suckers have to share a single voucher? Individual receipts would really be more hygienic,” writes one user.
The sign probably only found its place in the unspecified supermarket when snacking on deposit vouchers became so common.
