Today, at the Superfresh, when your cashier asks you whether you'd like anything else. Say to her, "No, that'll be all." Then take a pause to look at the nametag on her breast, and add, "Sarah."
The cashier will smile. "Actually, this isn't my nametag. I borrowed this from somebody because I left my nametag at home. But I appreciate you taking the time to address me by my first name. It seems like we all do everything we can to run from transaction to transaction, casting people out of our lives as quickly as we pull people in, making an effort to not remember a single detail of the strangers we meet in our day. I mean, if I place my fingertips to the skin of your palm when I hand you your change, are we really strangers anymore?"
"Precisely," you'll say. "So what is your real name?"
The cashier will say, "It's Sara, but without the H."
Ask to speak to the manager and complain that Sara without the H was getting nitpicky with you. Threaten to never shop there again and he'll give you some special coupons.
Happy Nametag Day!
