Short arms and deep pockets at Christmas

Last act of the day before finishing for the holiday? Checking to see if a very large corporate customer has paid an overdue invoice. The answer is, they haven't (despite an 'assurance' from an accounts wonk that it would be in my account by yesterday). So I'll be starting the new year in full on credit control/small claims threatening mode. Bah humbug. Happy Christmas - 'cheques in the post'
