(Keep in mind, this customer comes in about ten times a day. He’s insane and you never know what you will get from this guy.)

Customer: “Yabba dabba.”

Me: “What?”

Customer: “Yabba dabba.”

Me: “Okay. That will be thirteen fifty.”

Customer: *hands me money* “Yabba dabba.”

Me: “You don’t say?”

Customer: *angrily* “Yabba dabba!!”

Me: “Doo. Have a good day.”

Customer: *happy now* “YABBA DABBA!!!!” *leaves*

(He comes back about two hours later, talking regularly like nothing happened.)
