I just discovered you and listen to your podcast episode. I love it. Being the Agent of Positivity and encouraging others in becoming one is so important in today's world. As you said at the beginning, many people are feeling hurt. I worked at the retail store in the past and the scenario with a cashier and some negative customer was typical. But those who came and decided to be kind or simply nice, they often became unforgettable for me. We may think that our little gesture of kindness or positivity doesn't make a big difference but that's where we are wrong. We do have a positive impact on people, often without knowing it. Let's say like the cashier you mentioned. We may never see him/her again, we may never know how much of an impact our positive attitude had on them, but we may start a chain reaction where the cashier gets out there and share more kindness because of us.
