tesco staff is forgetful jz like me lol.
Aeon staff is good.
last time go tesco shopping when I pay my groceries, the cashier didn't ask/ remind me whether I am tesco member and direct scan all my grocery. After I paid only I realized that I forgot use my card to collect points.
When you go Aeon and paid, they will always remind / ask you to show the member card before paying the bill.
