It seems that that the hawker had snatched back a bracelet from the buyer when he spotted the latter leaving the premise. From their exchange, it seems the buyer had paid $2 for the bracelet earlier and went around exploring the market before the seller approach him when he was about to leave, accusing him of shortchanging him as the item was to be priced at $12. Both refused to relent on different principles. The hawker was adamant the buyer underpaid while the buyer felt that if the good has already been transacted, the hawker has no right to ask for more now. Over a difference of $10, I saw the hawker picked up a sharp, rusty instrument, looking as if he was ready to stab the buyer. Luckily, someone stepped in to calm both parties down.
