re: Qantas Restaurants that DO or DO NOT award points
There are 2 issues at play here:
(1) When the restaurants "give" you Qantas points they have to pay Qantas money. Therefore, it is in their interest if the "machine isn't working" or "manager doesn't know what to do" or whatever the excuse is.
(2) Earlier this year Qantas revamped the whole Qantas Frequent Flyer Service Centre. Instead of processing claims themselves, they now push back to the service provider eg hotel. Qantas used to take the details from you and then chase up the supplier for the points and credit them to your account. This is no longer the case - the Qantas department that did this is now much smaller.
Again, the same issues are at play when you go back to the hotel (or whatever) - points is money for them so it is not exactly in their financial interest to "give" you Qantas points.
I have got around the unwillingness of the Qantas Frequent Flyer Service Centre to help by writing to them.
A clear letter together with photocopies of receipts, boarding passes, credit card statements - all of the "evidence that you have" and posted (the old fashioned way with a stamp) to:
Qantas Frequent Flyer Service Centre
GPO BOX 4357
MELBOURNE VIC 3001.
Whilst it can take some time, this method always gets me a result. Qantas logs all incoming mail, then scans it and then it is dealt with by somebody - you can't simply be fobbed off by a 3rd party contractor call centre staff member.
