Spreading the virus
Think about how many people you come into contact with when grocery shopping. You’re constantly squeezing past people in aisles, workers are stocking the shelves next to you, and you pay at the till where some scan each one of your items. If you’re on self-checkout, just think of the germs on the touch screen display.
Meal kits avoid most of this. You don’t even need to answer the door to the courier, you can leave a note asking them to leave the box on your doorstep and walk away. There’s only the person that packed your food, but it’s likely they were doing it very quickly and with gloves on. This isn’t guaranteed, but there’s no doubt that going to the supermarket is more conducive to spreading the disease as opposed to meal kit delivery.
