Caught off-guard, I blurt out, “Kopi O Kosong!” hoping I nailed the pronunciation. She pauses, gives me a scrutinizing look, and repeats my order back, emphasizing every syllable as if to test my commitment: “Kopi...O...Kosong?” I nod quickly, like a student trying to pass a surprise oral test. She gestures towards a QR code for payment and rattles off the amount. As I fumble with my phone, she’s already moved to prepare my drink, her movements swift and precise.
