某楼房自出租后,房主便不断地接到房客的投诉。房客说,电梯上下速度太慢,等待时间太长,要求房主迅速更换电梯,否则他们将搬走。已经装修一新的接房,如果再更换电梯,成本显然太高;如果不换,万一房子租不出去,更是损失惨重。几天后,房主并没有更换电梯,可有关电梯的投诉却再也没有接到过,剩下的空房子也很快租出 Since the rental of a building, the owner will continue to receive complaints from tenants. The tenant said that the speed of elevators is too slow and slow to wait for too long, requiring the owner to quickly change the elevators or they will move away. Has been renovated a new room, if you change the elevator, the cost is obviously too high; if not change, if the house can not be rented out, it is even more heavy losses. A few days later, the landlord did not change the elevator, but the elevator complaint was never received, the remaining empty house is also quickly rented out
