The other day, at a supermarket.......
A cute little girl took an ice-cream from the small freezer near the exit. After that she toddled to the cashier at the counter nearby, raised her little hand and offered the cashier a one-dollar coin.
"Not enough. One thirty," the amused cashier said in English. The little girl did not seem to understand.
1 30, the cashier repeated, 1 30. Still the little one shook her head.
At this instance, a kind uncle who was delivering goods to the supermarket went to the girl, squatted down and explained to her. Whether she understood or not I don't know. In the end she toddled away, haha, probably going to look for her ice-cream at another shop.
