As soon as Nidhi said she wanted to leave, the servant became nervous and quickly said, "Actually, there is a power cut in the whole house. Can you stay a little longer?"
"It is already very late. I have to go," Nidhi replied.
"But the front door is locked now. You can't leave," the servant said, making her confused.
"The door is fully electronic. If the battery dies, it won't open," he explained.
"Doesn't the door have USB ports? Can we use a power bank to charge it?" Nidhi offered a solution.
The servant hesitated and answered, "The USB ports are broken."
"Is there no key for the house?" Nidhi asked.
"It is lost," the servant said again.
"Well, then replace the dead battery with a new one," Nidhi suggested calmly.
"There are no extra batteries either," he replied.
