How did you arrive at extra 500? I’m sure it could be an example, but this card will likely entitle to have treat for two. My understanding is any extra consumables cannot be billed along with this. They will be billed separately. You may also talk to the outlet for better clarity. Eventually you will be dealing with them,.

Yes it works..I have tried this..it’s a complete bill package..if you have hapiness card for two people then those two people will not have to pay any single penny more for bill amount. Happiness card for 2 means unlimited buffet meal for two with no other charges.
