Everyone has had the experience of going to a retail store to buy something. Whether it's food or anything else. When you choose a good need to buy things, get to the cashier to pay. Some cashiers will ask you a question: Is this the only one you want to buy? Often you'll say, "Well, yes. I've seen this happen so many times that I'm sure most people have been asked this question.
What I'm trying to say here is this: Whether you're a cashier who says it to humiliate the consumer, to embarrass the consumer and then go back and get a couple of things, or simply to vent your frustration at work.
In short, the waiter can say this kind of words store, the level is certainly lower. The reason is simple: it's hard to make a significant profit if you don't go for volume. But this kind of commonplace "guideline" that seems to have been "professionally trained" can actually promote sales, in fact, is also relatively small.
Because the customer was implied by the cashier, "Why did you buy so little?" Afterward. Instead of giving up on the checkout and choosing a few more products, they will feel even more humiliated. It would be better to reply without thinking: "Yes, just this one" And the waiter's seemingly inadvertent question is itself a bit of a forced buyer and seller. I don't think any customer would find it pleasant to be fed flies before the customer has even checked out. Since you think I bought less, then I can't afford to do something repulsive next time~.
