The sky is falling

Date: 5/6/2017

Set in the near future. At a grocery store was sitting down/ trying to take a nap while someone was shopping. Outside a huge asteroid starts coming down an hits about a few hundred miles away. The explosion expands and as soon as I thought it was going to hit us, the protective honeycomb looking barrier protects us. Everyone is trapped in this grocery store and we have to figure out how to survive.
