I don’t tip anyone who is being paid for performing their jobs unless it’s a “service” industry such as a restaurant or bar. The mail people earn their pay and receive compensation. I don’t tip my auto mechanic either nor the local police. If I were to go to a Starbucks, I know they have tip jars too. Not gonna tip them for doing their job as it’s their choice to work there. It would be like tipping the McDonalds cashier, no thanks.
