Helen didn't give you the winning lucky nos
Helen only provided a service to you (as with all customers and it's very normal when boxed out, the operator will help to punch in the combinations)
Helen serve so many customers a day, it's very unlikely she can remember who buy what and amount.
If have heart to give, then just give without 2nd thought of past losses cos this is like half-hearted appreciation
If it's just a "pure" sign of courtesy, a small token of appreciation ($688) is sufficient to show your appreciation for her service and can also ask Helen to help you to select 50 pieces of this coming Big Sweep tickets and 28 pieces of System 7 Quick Pick and $50 Ordinary Quick Pick for today TOTO draw.........
If you have other thought of appreciating her further (MILF, Fair skin in her 40) then jio her out for dinner when the other 2 aunties not around and use this lucky strike for consecutive strikes. You can give her your "token of appreciation" over dinner (accidentally dropping a box of durex is also good to break the ice when taking out your Ang Pow).
As for the other 2 aunties, it is purely optional ($188 for both but with these 2, better don't drop any condom hor), you can give next day or some days later, so Helen will know that "She is Special".....Giving the "Ang Pows" to Helen and the 2 aunties on different days also prevent the 2 aunties from comparing the weight of the "Ang Pows". It is also better to let Helen know that her "Ang Pow" is heavier than the 2 aunties but keep it discreet and remind her that when the 2 aunties check, just tell them she is receiving $188 also, this is to avoid unnecessary gossip which might ruin your chance of a "Double Strike"
Finally, operators only doing their job, better to be generous to your family, friends, donate some to charitable organizations and save a large % of it for raining days. Have money must think of No-Money days
