Hell yeah.At least they can still sell beer!
It happens maybe once every 5-10 years. Like you said, bad luckThey really couldn't afford to have another delay due to a random flash up in the clouds. Now they likely won't be able to finish before the more flashy stuff reaches the area. At that point it could go late into the night if they even want to bother finishing.
Until tonight it had not stormed around here in weeks. It's just bad luck.
