Beer for breakfast???

Yummmmm. So the work guys showed up this morning to lay the 5cm of concrete on our terrace. Good news: we're making progress on the terrace project. Bad news: They're drinking beer while they do it. Yes, at 8:00 am, nothing satisfies thirst like a Czech beer. At least there are no power tools involved. I'm a little worried that in a few months they may need to come back to redo the terrace once again?
