There are people out there working, doing their jobs to the best of their ability, with staff shortages, shipping delays, product shortages and so much more in the way of providing what we use to take for granted. This is widespread. Practice kindness. Everyone is dealing with the same stresses that you are, only if they work with the public, their stresses include dealing constantly with increasingly crabby and angry people.
Cut everyone a break. It’s time. Kindness can change someone’s whole day, and maybe their whole outlook.
