A local retiree has been lauded for her selfless commitment to public health after performing open-heart surgery on strawberry punnets in Bedok.

Armed with unwashed fingernails and a sociopathic disregard for salmonella, the amateur fruit geneticist meticulously transplanted the juiciest berries into her "God-tier" box.

Witnesses claim the woman spent twenty minutes ensuring every single berry was thoroughly palpated to confirm maximum value.

"Liddat then worth the money mah, you think the fruit grow from tree for free ah?" remarked one supportive onlooker.

The supermarket responded by replacing security guards with signs that read: "Please touch the produce until it loses its will to live."
