Not necessarily. In Serbia and other ex-Yu countries, there are three basic ingredients to a workday: coffee, burek (urda cheese and philo dough pie, pizza-sized, you get a quarter - about 250g), and liquid yogurt (a bit thinner but fermented further than what you can buy here). Anything else can be missing - power, staples, paper, phone lines may be down, whatever happens will not hinder the process. But if one of the those three is unavailable, there'll be trouble.

So you see, there's a whole country where people have no habit of drinking pop during work at all. Carbonated drinks? That's for kids. Mineral water (which is carbonated :) with the coffee, that's OK. Sugar water, no.

Maybe today they do, I'm out of the loop, but I really don't remember. We did have beer a few times, when we expected no visitors ;). And in some places there were stiff drinks at hand, for sufficiently important guests or at the end of a hard day.
