With all the stores still closed and curfew in full effect, Nikki and Mark got into a discussion about what is essential for each store.
Sam broke his sunglasses recently and believes they are essential to driving. So he called different stores to see which stores think it's essential and which stores don't.
Mark's microwave blew up and he figured he couldn't buy one because it is not considered essential. Nikki thinks it is essential so she called a few places.
