I have seen many food delivery workers (they are all contractors, of course) who brag about stealing food from bad tippers. I am not a bad tipper, and delivery drivers steal the drink from my order all the time. In fact they did it more often when I just ordered one drink; now I often order two, and I find that it comes in a carrier and they leave it alone. Perhaps it's a huge bother for them to wrestle one lonesome moist cup, and they'd rather keep it for themselves.
If I do decide that the driver caused some big problem or outright stole from the order, I will pursue customer service to reduce the tip to $0. They don't always understand that, so I have to spell it out. And yes, I do increase the tip when I find that exceptional service has been rendered.
While true, it is just veiled and normalized in 1st World nations and perhaps more pernicious due to severity; at least it's honest in the so called 3rd World as you mentioned which ironically makes it more tolerable to me.
I don't like it, but I'm also beyond the hope we can undo this until an immense reduction in population makes housing, and the maintenance that supports it, a post-scarcity commodity which I fear will likely never completely happen.
