You were walking outside the street with a bag when suddenly someone came running up to you and stole the bag from your hand and ran away. The guy who was behind you noticed how the stranger stole your bag so he chased after him.

A few minutes later he returned with the bag that the stranger had stolen from you and handed it to you.

"Here is your bag" he said with an agitated tone, you thanked him and you grabbed the bag from his hand and then threw it in the trash, apparently it was a garbage bag, the guy looked at you with a embarrassing face.
