Customer: “Why won’t your gas pump accept my credit card?”

Clerk: “Sorry, it’s cash or debit only.”

Customer: “But I have a credit card and it won’t take it!”

Clerk: “Cash or debit only, ma’am.”

Customer: “This is a credit card!”

Clerk: *pause* “It’s cash or debit only, not credit.”

(The customer finally realizes what the clerk’s been saying and automatically becomes huffy.)

Customer: “Well! Y’know, giving me the same answer three times doesn’t help me understand. You should have said, ‘we only accept cash or debit’. How was I supposed to understand what ‘cash or debit only’ means? It’s not a complete sentence!” *storms out*
