You can't fill it with water, which is a courtesy and a respect for each other. Because the water is hot, if the whole cup is full, it will be very hot, so guests can't drink from the cup, so leave a certain space when pouring water. Generally speaking, seven minutes is enough. This is also common sense, as a college graduate, this truth should be known.

But the company poured too much water, and there is no reason to dismiss employees, which is a bit far-fetched. Can't understand. He may not understand this, in this case, he should be given a hint to tell him not to pour too much water next time and explain this to him. He will pay attention to this problem the next time he pours water. If he still doesn't change, you can dismiss him for this reason.

When new employees enter the company, they need someone to take care of them and train them. If you don't even know this basic etiquette, then the company is also responsible, at least not trained in it. Of course, this college student is still on probation. During the probation period, if it is found that the company does not meet the employment conditions or has other fault conditions and can be dismissed without fault, the employee may be dismissed. However, there is no fault, and dismissing workers requires certain economic compensation.

I think this company just doesn't want to hire this employee again, but it shouldn't be used as a reason to dismiss him. It should find a more reasonable reason. Maybe the company didn't want to give him financial compensation, so it dismissed him on the grounds that the water was too full and put the blame on the employees.

However, if I were this employee, I would leave directly, because such an organization is not worth my nostalgia. This is an impersonal company. No matter what it says or does, it lacks human feelings and the minimum respect for employees, which makes people feel indifferent.
