So, how can GP get around awarding points for alcohol in Australia if the T&C says the following:
WHAT IS ELIGIBLE FOR EARNING AT RESTAURANTS AND SPAS?
Eligible changes vary on a hotel-by-hotel basis, but generally include spa and salon services, spa and salon retail items, and food and beverage expenditures (except at outlets not operated by the hotel). Points will not be awarded on tips, service charges, taxes, gratuities and alcoholic beverage purchases in certain jurisdictions. (Alcohol excluded where prohibited by law). Other exclusions may apply.
The PH in Sydney simply refuses to award points for alcohol and I don't know of any law in Australia that would make alcohol illegal.
