Reason:
First, your hesitation will make employers misunderstand that you have other secrets (accommodation and wages, etc.). If they think you are qualified, they will definitely try to solve your problem instead of letting people go directly.
Second, you went around and didn't go at last, wasting the company's energy and time. You think it is polite to do so, but in fact, you finally left a bad impression on the company. The company is a place that pays attention to results and efficiency. If you don't go, please let the other person know clearly at the first time so as to continue to recruit people.
The more euphemistic, the more sign of delaying everyone's time.
