I had a safety training yesterday. During that time, trainer said the speed limit is 10km/h for the specific vehicles. But there is no speedometer. So I asked like if there is no speedometer how can we know speed? And american guys tried to answer me and they said it was good question. But after the training, korean coworkers said "you wasted our 5minutes. Why did you ask unnecessary question?"

I thought that I hate Korean mind. My question is is it normal situation in America or the other country?

My personality is that I have to accept or be convinced. Is it my problem?
