Rather than spend time and energy bringing the thief to justice, the savvy business owner decided a sign calling their actions out was perfect for the job.
"To the creep who STOLE the hand sanitiser we made available for our customers' use," the message declared.
"You are a despicable, selfish person. We hope Karma bites you on the a*se!"
Henderson told news.com.au he had absolutely no qualms whatsoever about posting the message as he was gobsmacked by the person's "foolishness".
"I am the type that will call out foolishness when it appears in front of me," he said. "It's incredibly selfish to take something that I've made available to everyone who comes past."
While security footage has been reviewed and confirms the culprit was a woman who Henderson had been speaking to, he doesn't plan on taking the matter further.
However, this doesn't mean he would not want her to feel guilty should she happen to walk past the sign and its strongly worded missive.
According to Henderson, the sign has struck a chord with those who've seen it, with many stopping to have a bit of a chuckle or to take selfies.
"The response from people walking past has been great. Hundreds have stopped at the sign to take a photo."
He said while his sign is taking a dig at the person who swiped his hand sanitiser, he hoped the humour might lighten up a very serious situation.
"This is a good opportunity to be a bit more mindful of those around us."
While health experts recommend washing your hands for at least 20 seconds to keep them germ-free, hand-sanitiser is also a must.
The Centre for Disease Control recommends using hand sanitiser when you can't get access to soap and water to clean your hands.
According to the Department of Health, a hand sanitiser that contains at least 60 per cent alcohol is most effective.
Research from the University of Toronto has found that hand sanitiser which contain 70 per cent alcohol is the ideal amount.
"That's the concentration of rubbing alcohol that is most effective in killing germs — it's even more effective than 100 per cent. Because it has a little bit of water in it, it improves penetration," Professor James Scott said in 2012.
A shortage of hand sanitiser is being witnessed in multiple retailers across the country as people rush to stock up in a bid to protect themselves from the deadly coronavirus sweeping the globe.
