Because the cost of milk tea is much higher than Sour Plum Soup, Ni Yang plans to sell it for three cents a cup.
Although the price is a little higher than Sour Plum Soup, compared to drinks like Jianlibao and Dabaili Soda, it's a lot cheaper, so diners can accept it.
"Little boss, your milk tea is good. I'd like to take a cup back for my son to try. Could you give me an extra one?"
Ni Yang smiled and said, "If you order another bowl of noodles, I can give you an extra cup."
With so many customers in the shop, she couldn't break her rules. If she gave everyone an extra cup, she wouldn't need to do business anymore.
"What if I buy it alone?"
Ni Yang explained, "If you buy it alone, it's three cents a cup. The promotion of getting milk tea with noodles is only for today. There won't be any tomorrow morning."
"Alright, then cook another bowl of noodles for me."
Only a fool would buy just one cup.
