I was running a poker tournament this evening. The type of tourney is freezeout with up to a $25 dollar add-on worth 5500 in chips. I seated him, gave him the starting stack plus the add-on, and told him that I needed the marker from him which signified he purchased the add-on. At a later point, he had the marker on the table, which is in play, and when he went all in, he was awarded an additional 5500 in chips, due to the in play marker. How would I penalize/fix this situation in the event that my attention is not drawn to the error immediately?
