At that moment, all eyes were fixed on Zhang Xiaowei.
He approached the counter unhurriedly and, after casting a disdainful glance at Cao Yuming, extended his hand toward the man who was leading the troublemaking.
"Fine, since you want a refund, I will give it to you, bring out the receipt."
The man was immediately dumbfounded upon hearing this.
"I threw away the receipt, I don't have it."
Zhang Xiaowei knew for sure they wouldn't have the receipts.
After all, these fake medicines weren't bought from here in the first place.
He didn't rush to question them, instead, he looked up to ask the others, "What about your receipts?"
One by one these people were left speechless, shaking their heads one after another.
"We don't have the receipts either."
"Right, who keeps such things after buying medicine."
"I threw it out right away."
Seeing their indifferent attitudes, Zhang Xiaowei scoffed and shook his head.
