And The Survey Says: Chili's is going to do me wrong!

I completed an online survey after visiting my local Chilis. It says I am eligible to win a cash prize. Notice the amounts under "Eligible Prize(s)".   It quotes the prize in US Dollars, Canadian Dollars, British Pounds and Euros. I wonder if I have a choice of currency to receive my prize?

Here are the currency conversions at the latest exchange rates:

$1,000US = $1,000US
$1,000 Canadian Dollars = $982.28
1,000 British Pounds = $1,601.91
1,000 Euros = $1,377.82

Long Live The Queen!!  British Pounds, please...
