So here’s what we know works.
Smile at the customer. Take the initiative. Tweak a few rules. Steal cookies for your colleagues. Don’t puncture the impression that you know what you’re doing. Let the other person fill the silence. Get comfortable with discomfort. Don’t privilege your own feelings. Ask who you’re really protecting. Be tough and humane. Challenge ideas, not the people who hold them. Don’t be a slave to type. And above all, don’t affix nasty, scatological labels to people.
It’s a jerk move.
