Even our stove at home isn't this clean. To claim that it's not up to hygienic standards is to nitpick.
An older busybody woman couldn't help but enter and have a look around. She immediately echoed, "It is indeed very clean, not a single speck of dust, fridge and stove are shiningly polished, no issue with hygiene. Could you have made a mistake, young lady? I frequently buy their milk tea for my grandson, and there's never been a problem."
The reason she came in to inspect was to evaluate the cleanliness, so that she could feel at ease buying milk tea for her grandson in the future. The shop was indeed very clean, much cleaner than her own kitchen at home, so there was no room for complaint.
"Exactly! What if your son ate something else that made him sick? Don't falsely accuse the shop, it would disrupt their business."
"Indeed, our school students often come here to buy milk tea, and there have never been any issues in over a year."
