You cut the bar into a $1,000 piece, a $2,000 piece and a $4,000 piece. The first day you give him the $1,000 piece, the next day you take that piece back and give him the $2,000 piece. The 3rd day you give him the $1,000 back, and the 4th day you take the $1,000 and the $2,000 back and give him the $4,000. The 5th day you give him the $1,000, the 6th day you take that back and give him the $2,000 and on the 7th and last day, you give him the remaining $1,000 piece.
