Rock, paper, scissor

In front of a hotpot restaurant, four sports bike stopped, one after the another.

ZouMi was first, then Chen, followed by Bai and Xau.

"Say what, the one last have to pay the bill?" ZouMi said, as she removed her helmet.

"We still stuck there? Come on, richy rich, pay, don't be so stingy." Chen gave her a dirty look.

"Sis, you want your brother to be broke?" Xau complained.

"There we go, two shamelessly rich twins, talking about being broke!" Bai scoffed.

"Unlike you, filthy rich, poor doctor." They won't hold back in getting on each other's nerves.

The passersby kept turning their necks, to look at these four, who didn't give a damn about anything, looking like arrogant rich second-generation kids.

But, to their astonishment, these kids are self-made, millionaires, and the girl was billionaire. And the passersby could never know about this, so they just silently judged them and walked away.
