She stopped by a new stall selling onion, garlic and spices opened by an Indian man to buy onion and garlic.
As she was picking the onion, she asked the owner, "How much is one kg?"
The man replied, "$4."
The lady repeated, "$4?"
The man placed his index finger to his lips to gesture to the lady to lower her voice.
He then whispered to her not to let the lady owner at the next stall to know how much he is selling.
Apparently, the lady owner came and told him off for selling the onion cheaper by $2 than her.
