I went to buy a sports drink to the bending machine close to my office.
At the vending machine, the drink costed me 160 yen, but I only had a 1,000 yen bill.
So, I put that in.
When the machine was giving me back the 840 yen for the change, I dropped all the coins on the ground by accident.
I was looking around so hard since it was dark already.
After I spent few minutes, I could find all my coins.
I counted them again and after I made sure I have all the coins, I went back to my office.
When I got back to my office, I remember that I forgot the drink I bought in the machine.
