Phar­ma­cist: You should prob­a­bly re-sign your card.
Woman: Why?
Phar­ma­cist: Well, you signed over the mag­net­ic strip. You’re sup­posed to sign over the white part down here.
Woman: Then how would the ma­chine read my sig­na­ture? That does­n’t make any sense.
Phar­ma­cist: No, it’s a mag­net­ic strip. It reads the in­for­ma­tion, not the sig­na­ture.
Woman: I don’t think you know what you’re talk­ing about. That’s not how the ma­chines work. You’re a phar­ma­cist, not an elec­tri­cian.

Then the phar­ma­cist gave up.
