He submitted a video of the incident that occurred at around 6.30pm.
Thomas shared his account of the incident: "I saw this young couple walking towards me and noticed that the woman was not wearing her mask.
"I hand-signalled to them and showed a hand gesture several times to ask her to mask up, but she ignored me.
"I took a video of the couple walking past me in case contact tracing would be required.
"The woman reluctantly masked up only to her mouth and avoided her nose. Out of concern, that was when I told her to 'cover your nose and protect yourself'.
