You're in a hurry, waiting in line to checkout1 and something happens to slow the line down. The customer in front of you has brought 20 items to a 12 item express lane, a price check is needed and no one is around to do it, the computer system goes down, etc. It's enough to make your blood boil.
你在赶时间，排着队等结账，可前面出了情况，让等待的队伍前行缓慢。排在你前面的客户买了20样东西，却排在12件以下迅速结账的队伍里；有件产品的价格需要确认，却无人理会；或者结账的电脑忽然坏了。如此的各种情况都大概让排队的你怒气上涌。
Here comes the checkout rage or checkout line rage, which refers to extreme anger caused by a perceived wrongdoing or a lengthy2 wait in the supermarket checkout line.
这就是大家所说的收银台怒或者收银台排队怒，其实就是在超市收银台前排队结账时等待时间太长，或者由于发生了别的情况而感到异常恼怒的状况。
