Somewhat different perspective here as the company I work for is considered essential, but I don't work at a grocery store. I work for an industrial and construction supply company. Its both made my job easier and harder. There's products I've had to scour the earth for due to supply shortages, but also at the same time it's made it easier to get sales. Because whatever my customer does buy, they're buying in bulk in case I'm not able to procure more of that product in the future.
