Going On A Playful Trip

(My dad and I are walking down towards a small cafe when we see a man burst out running and a waiter follow soon after.)

Waiter: “Stop! Stop him!”

(My dad looks uncertain but sticks his foot out and trips the ‘runner.’)

Runner: *falls and curses*

(The waiter catches up and pins him against the wall. Later we see him drag him away back to the cafe.)

Me: “Wow, such action.”

Dad: “I thought they were playing because they were smiling!”

Me: “Then why’d you trip him?”

Dad: “…”

(When we ate at the cafe the waiter gave us 50% off!)
