Washing a hand

I worked for the company which sells an office appliance before.

I might go to a customer to clean the appliance.
My hand is stained when I clean the inside of the machine.

I left the customer with blackened hand in ink and oil.
In a near restroom, I washed my hand immediately

One day I washed my hand in the restroom of the station.
I think that I was considerably eagerly.

A woman of the restroom cleaning watched me and said.
"Will I sprinkle a detergent?"

Immediately she sprinkled a detergent for cleansing in my hand.
She pulled a cleansing tool and left the restroom.

Finally she said to me.
"It washes it off well"

At cold time, water was very cold.
The detergent really washed off a dirt.

A woman of then, Thank you.
