Never take an economist to yum cha
'Shall we split the bill then?' The economist asked with a cunning grin
Have you ever tried to win at yum cha? No? Good for you. I promise there are those of us who do. You know who you are, you rational consumer you.
What does it take to win at yum cha? Simple. Eat the most.
At yum cha, the bill is usually split evenly between the people at the table. So there is the risk you end up subsidising somebody else's meal if you don't eat enough. Best to invite your smaller friends.
