She bought a lot of snacks.
The cashier was scanning her items when the lady suddenly stopped her in a rather loud and rude voice.
"Excuse me, this is 1 for 1. I see that you scanned twice?"
The cashier did not answer her and proceeded to recheck that the discount is reflected in the system.
After the cashier scanned all the items, the lady took out a Gucci wallet that matches her handbag and flip out her credit card. As the cashier was processing her payment, she tried to search if she has enough cash to pay for her purchases.
That's when I saw her Singapore Pink IC inside her wallet.
Hope that she realized by now that discount will be automatically populated in the system after the items are scanned.
At least be humble to ask politely.
