Text: The Shopping Avenger, while not identifying himself as the Shopping Avenger--this would have meant changing into his codpiece and cape in the business-class lounge--informed this poorly informed British Airways employee that the Shopping Avenger was America's foremost consumer advocate (this is a lie, but she's English, so what does she know?)
Entailment: The Shopping Avenger is American.
Contradiction: Hi shopping adventure was not rewarding.
