American fast food restaurants drink whatever they like. Why do people want to spend more money on large cups?

In fact, the prices of these different capacities are different. For example, the price of a small cup is the cheapest, but the price of a large cup is much higher. In fact, the three intermediate prices also need to differ by several yuan. Under normal circumstances, if we drink less, we will choose a small glass in particular. However, if we drink too much at one time, we will especially choose a large cup of milk tea. Almost no one will choose a medium cup, and think that buying a medium cup is not cost-effective, and a large cup is more cost-effective.

In the same store, cups with different capacities are specially selected, so he first pours water into the middle cup, and then after the middle cup is full, it can also measure the capacity. The water capacity of the medium cup is 5 ml, so he filled the large cup, and the measured water capacity is 67 ml, which means that there is a difference of 17 ml between the medium cup and the large cup, but the price difference is two yuan, so it is really more cost-effective to buy the large cup.

when consumers switch from buying a small cup to buying a large cup, consumers and stores achieve a win-win situation. For the store, the increase from small cup to large cup only needs to increase a part of the cost (which is obviously lower than the price difference between large cup and small cup), thus bringing more profits to the store. For consumers, because stores are willing to provide more discount space for large cups, consumers can enjoy more discounts.

The packaging of these drinks is actually tricky. After all, we have added money, so there will be a little more drinks, but the gap is not obvious. However, most of these drinks are sealed. Sometimes, this amount is more or less up to the store, so it is easy to hold a large cup in a medium cup. When you drink it next time, you should polish your eyes.
