Yes, you don’t always have to be a Karen.
Remember the saying that you should not do unto others what you don’t want them to do unto you?
It takes humility to see that the people you are engaging with are somebody’s mother, father, sister, or brother. And that treating them kindly, especially when they’re trying their best to meet your need as their customer, goes a long way.
Your kindness will come around eventually. And the next time, you’ll be on the receiving end.
