20% capacity means 80% don’t get in.
Doesn’t WM have any industrial engineers on staff? It’s not that difficult a concept to understand that the conga line inside the store will advance at the speed of the slowest shopper (at best).
It was in the 90s here last week. That will work well in the afternoon at my WM with a west facing front.
That capacity is the fire marshal limit based on the store sq footage. I doubt that it gets approached very often or ever.
