First game, first black mark

I'm sat on the PC minding my own business when an email comes in from the club secretary. I forgot to score the referee and sign the official match form after our first game. This offence normally carries a £15 penalty however the league have been lenient and have said that if I go and sign it they will let us off on this occasion. A simple phone call to the league official is all it takes and a date and time is arranged to sort out the paperwork.
