(This just happened to my fiancee and I yesterday while we were trying to purchase tickets for a concert. My woman had a bad cold, bordering on laryngitis.)
Woman: Two Achoo! tickets, please.
Clerk: Have you purchased tickets here before?
Woman: cough No.
Clerk: Then I need your address.
Woman: Okay. It's 260..*AHEM* Sorry..Laryngitis...
Clerk: You'll have to spell that one for me.
