I never ate at A Lorcha http://www.flyertalk.com/forum/china...on-44.html#660 again - I've found way better restaurants in Macau to go to. I never bothered to contact them after the meal either - I don't know if they have an email address and I'm not paying for IDD if I can avoid it.

I imagine one of two things happened:

1. My issuer took the HK$562.73 back. Banco National Ultramarino deducted MOP564.30 from A Lorcha. A Lorcha asked BNU to charge me again in MOP this time based on their merchant copy and the slip was re-presented.

2. My issuer took the HK$562.73 back. As BNU already had the copy of the slip it recharged my issuer MOP564.30 without reference to A Lorcha.

Unless a Citi Prestige-like offer comes along it'd be more worthwhile for me to use Unionpay in Macau - Unionpay rate is competitive here, no foreign currency translation charge and decent $6/mile earn rate.
