Staff at St Regis Singapore got finally things sorted out for this promo. No more stupid questions and I was given what I should get:

- complimentary glass of wine
- 15% discount (although I had to ask for it upon getting the bill)
- 10% comeback voucher

In fact the lady who brought me the bill said at first that I could either choose wine or 10% comeback voucher but since I opted for wine, no voucher. She came back however apologising and brining comeback voucher as well. It is called triple delights after all, right?

Now reading T&C of the comeback voucher it says that:
"Offer cannot be used in conjunction with any other promotions, discounts, vouchers or loyalty program."

But triple delights highlight states:
"Great comeback. Join us for a meal from July through September and get a chance to dine with us a second time with an additional 10% off your tab. Voucher valid through October 31, 2013."

Does it mean dining next time I can get 15% + 10% off or just 15%?
