Meng Zhao's bowl is larger than the ones used in ordinary households. If it were sold separately in the shop, it would cost about five or six coins. However, in the eyes of diners, buying exactly twenty coins would seem more like a better deal than a 20% discount.

However, Meng Zhao's cost for each bowl is three coins, which is higher than the profit margin of a direct 20% discount. Moreover, if you buy 30 coins worth of bowls and get a bowl for free, Meng Zhao's profit will be even higher.

This indirectly increases the unit price in Meng Zhao's shop, and most of the diners who bought more than ten coins would be willing to spend a few more coins to get an extra bowl.

Moreover, Meng Zhao stamped the Meng Family logo on each bowl and basin, so that customers could see the logo every time they ate at home, subtly increasing their impression of her shop.

Although banners were posted, not many people could read, so Meng Zhao had Shen Yun and Lady Liu each carry a food tray, serving samples while shouting promotional slogans.

Shen Yun had done this job before and was now very skilled at it. Her face was flushed as she shouted loudly, "Meng Ji Braised Pork is having a grand opening sale! Spend over 20 coins and get a free large bowl. Once they're all gone, they're gone!"

"Come and take a look, everyone! We have a variety of braised dishes for free to try. One bite and you'll love it; two bites and you won't be able to leave. Everything is free to try, so why don't you come and give it a try?"

Before long, a crowd had gathered around Shen Yun. At first, Liu Niangzi hesitated to speak, but seeing that even a young girl like Shen Yun could shout at the top of her lungs, she naturally couldn't be outdone, so she joined in the shouting.

"Mengji Braised Pork Offal Grand Opening Special: Free Samples Available! Buy Only If You're Satisfied!"

Both of them had clear, bright voices that made people feel cheerful. Gradually, they called out to passersby, and those who tried the samples rarely didn't buy anything. Before long, a queue formed in front of the shop.

Modern trendy shops even hire people to queue up every day because the more people in front of the shop, the more likely passersby will think that the shop's products must be exceptionally good. Even if they didn't intend to buy anything, they will be piqued and come over to see what they sell.
