Dude. This is nothing. Barclays charged me £22 for going £10 into my "reserve" overdraft for just 24 hours. Which is some completely absurd annual rate, 10^184

Dude. This is nothing. Barclays charged me £22 for going £10 into my "reserve" overdraft for just 24 hours. Which is some completely absurd annual rate, 10^184 % if my quick calc is correct (220% daily rate compounded for 365 days).
