One dollar

I bought two ham sausages and spent four yuan.

In fact, these two sausages only cost three yuan.

So, after a while, I asked the aunt who was selling things, "Two dollars for a ham sausage?"

"Yes, two dollars a piece."

In order to refute my aunt and safeguard her rights and interests, after about two hours, I went to another supermarket on purpose.

For me, every word of the ham price information in this supermarket is hopeful and heartstring.

Excited, I calmly took pictures and returned to the previous supermarket.

"Aunt, two ham sausages are three yuan. You're asking for an extra one." I showed the picture to my aunt.

A detailed oral communication...

"That's all right." My aunt took out a dollar coin and handed it to me.

I went back to my dormitory like a victorious soldier.
