OK, I have encountered a situation and was curious about what everyone thought.
I booked with a lady for today. We set the time, place etc. As we were booking through P411 I just trusted those rates and took the appropriate amount out of the ATM.
When I got home I sent an email to confirm and, just out of curiosity, looked at her profile and noticed she has since changed the rates.
I'm not going to complain about the rates (they aren't outrageous or anything) but I am curious what everyone's thoughts are. Should I be expected to pay the rate there now, or the rate that was there when I booked?
