Doesn't anybody work in those small shops?
> There's a mid-morning and late-afternoon snack
The mid-morning snack is not generalised and the late-afternoon snack is mostly for kids (after-school "merienda").
Edit: to be clear, I agree that most people doesn't have siestas and three-hours breaks only remain common in some sectors (retail) and places (small cities). The original article doesn't make much sense, by the way.
It's not a break if they make up that time later. Sounds more like working a shift, and then starting a second shift later.
Rephrase the original comment for a brief rest when working: "if you make up that 5 minutes later, then it's not a break". It's a nonsensical comment.
