Drinking bet ends early

Any drinking that Mark 0tto did Friday or Saturday did not violate the bet he made with me nine days earlier.

Last Wednesday 0tto bet me $50 that he could go two weeks without alcohol. After nine days of watching him drink Coke and iced tea, I conceded victory to him. We came to an agreement that allowed him to win the bet, resume drinking and collect partial payment. I gave him $25 but then stuck him with the tab.
