The Problem With Blank Checks, Part 2

(I’m standing behind my counter when a man comes up to me with a prepaid phone and airtime card in his hand.)

Me: “Can I help you, sir?”

Customer: “I wanna buy this.”

(I usually make people tell me what they want before I just “hop to.”)

Me: “That’ll be $63.55.”

Customer: *sets check down in front of me* “Just fill that out for me.”

Me: *thinking about writing a check for $20 over for a tip*
