Bren-that is frustrating. But hold your ground, especially if you do not know the person hailing the cab for you.

I say "no thanks" to taxis all the while I'm here. I've never had a problem flagging one down, even if I've refused a ride from one previously for one reason or another. With the white plated taxis I also say no thank you but don't go into explanations as to why I'm declining the ride...the most "hostile" it ever got for me was leaving the donkey races last year when one practically ran me over to try to get me to take a ride - and I already had my driver coming to pick me up!
