"brah brah brah   1,500 W   brah brah brah"

(That is, lots of Korean writing, with the big sale price of 1,500 Won.)

1,500 Won! What a bargain! My son needs new sneakers, I have less than 10,000 W on me, this is serendipitous! Those babies are mine!

I choose the pair of sneakers. I go to pay.

Then the sales assistant weighs the sneakers.

Turns out the sale is 1,500 W per 100g.

Of sneaker.

Who sells sneakers by the gram? 

It was obviously there somewhere in the fine print.

In Korean.

What’s the Latin for stupid naive Korean-illiterate foreigner?
