Limited quantity, first come, first served.

I guess you have also received some short messages about activities and promotions of institutions or shopping malls. If prizes are involved, the text message is likely to end with a sentence: the number is limited, first come, first served.

Seeing such information, I often need to calm my slightly abnormal mood and say, get out.

This is an insult to every participant, insulting the participants as short-sighted mercenary idiots.

In fact, it's normal to have a limited number, and it's okay to come first served. However, at least tell me what the limit is. The rules are as transparent as possible, indicating the attitude of the organizers, which is the premise to ensure the fair participation of participants and the minimum respect for participants.

There is nothing wrong with not looking up at the customer, but there is no need to look down? After all, people are customers!
