Look after the pennies

Gala.  Giving away money again.  This is not how casinos are meant to operate.

I deposited £10 for today's bonus and it didn't work.  So I tried transferring the money via my poker balance to see how much they'd sting me on the exchange rate.

I started with £38.22.

I transferred £20 to poker, which was converted to $30.62.

Then, I wasn't sure whether the amount to transfer back was in pounds or dollars.  I entered "20" in the currency-less field and pressed "go".

That meant $20, apparently, which converted back at £13.07.  Then I transferred the remaining dollars back to pounds.

I made a penny.  In fact, I made two.  After I noticed this had happened, I had to try to reproduce it to get the screen grabs above.

I've contacted customer support about this.  While the idea of making a bit of money Office Space (or Superman III) style is attractive, PMITA prison is not so much.

EDIT: Bizarrely today my balance shows as £38.22 on the homepage and £38.23 in the cashier.  Looks like they are storing balances internally accurate to fractions of a penny, then rounding differently in different places.
