Paul likes to bet on the football. Each morning, he places bets on which team will win the day's matches. For each bet, he will either win or lose, depending on the outcome of the match. The matches start and finish whilst Paul is at work.
Every day, he walks to work, spends his day in the office, and then travels back home. On his way walking home from work, he sometimes checks the results of the day's football matches on his phone. However, sometimes he forgets to do this, and instead he checks the results once he has arrived home.
On the days he checks on his way home, he always loses more money than if he were to check after arriving home. Why is this?
