Increase the supply

No one expected Song Yixu to reply like this thus they were a bit surprised. Upon seeing the expression of the Yu family members, Song Yixu chuckled softly and then said with a teasing smile, " I am unhappy because I was going to ask Sister Dong to triple the vegetable supply for my restaurant and no, I am not doing this because I think that I owe her. It's because the demand for vegetable dishes has increased in my restaurant and I need Sister Dong to help me out. But if you are opening the restaurant then how will I put forth a request like this?" 

" Triple?" Yu Dong frowned when she heard Song Yixu's words, with her lips pursed she thought about something and then said, " If I am not wrong you are getting two hundred catties of vegetables every day. Yet they are not enough?" 

What kind of customers was Song Yixu getting? Even two hundred catties of vegetables were not enough?
