Well if you drove a total of 3 hours both ways to go home and rest and then return the next morning at a cost of $25 for gas. However, if you stayed and played the previous night at the same machine for 5 more hours with an negative expectation hourly loss of a just say $1 an hour "regardless of whatever actual result" Mickey was right you saved $5 because you did go home and the driving expenses was a wash anyway as you still had to leave at some point and return at some later point in time.
