Connecting with each and every person

How many people do you contact in a day that you do not make a connection with. The person at the gas station. The cashier at the grocery store. The bank teller. I have recently started focusing on making eye contact with each and every person, smiling, connecting, and saying something appreciative like “Thank you for being here today to accept my deposit.” Or “thank you for the quick and accurate checkout work.” Who is willing to do this with me?
