Right, I agree with you. I'm old enough to have noted the shift towards being more careless/less hygienic. I wonder why. You mention Westerners, well I'd probably agree with that too (but that's a trivial sample of two—a proper survey is needed). By contrast, when in Japan I noticed many, many instances of food preparation to be particularly hygienic.

It's interesting to note I purchased a Vietnamese-style bread roll for lunch today (presumably the owners were originally from Vietnam), and noticed the woman serving me had only one protective glove on—on her right hand. What was particularly noticeable was that she prepared the roll with her gloved hand and put it in a new paper bag without her other glove-less hand touching anything (tongs acted as her second set of fingers). At the cash-register I handed her a $50 note and rather clumsily with her left hand she deposited my note and returned notes and coins as change without using her gloved hand at all. Clearly, she was very conscious of hygiene. Why her and rarely others? Incidentally it was a small family-owned shop so the woman wasn't just acting out the hygiene requirements of say large chains like McDonald's.

Moreover, as COVID has diminished I've noticed very few now wear masks but the vast percentage that still do are Asians (BTW, I'm in Australia which is a mixture of every nationality).

Take from that what you will.
