To celebrate Shrove Tuesday I though I would share a recipe of how to create your own PR pancake disaster.
Place the ingredients together in a bowl and whisk together for 5 minutes. The 160,000 customers should separate and float to the top quite easily.
Remove the 160,000 customers and write to them informing them that their accounts will be cancelled in 35 days.
Release a press statement stating that you are closing the accounts of people who you feel pose a 'high lending risk'.
Poor remaining mixture down the kitchen sink along with any vestige of loyalty from your customer base.
