The mandatory requirement to wear a mask in public has been in place for a long time, but I still see people not wearing a mask at food centres or shops.

The only way to educate this group of people is to ban businesses from selling to anyone not wearing a mask. If they still choose to sell to such customers, then these businesses should be fined a substantial amount for encouraging this risky behaviour.

On Tuesday, I witnessed an elderly man queueing to buy food while not wearing a mask. He was allowed to buy food and I believe people like him will continue to do the same every day.

If you stop businesses from selling to customers without masks, they would have no choice but to comply.
