Do you do the same?
If so, have you ever noticed if someone used your detergent?
Have you ever used someone's detergent? Perhaps you forgot to bring yours or ran out and really really needed to wash clothes.
Have you ever removed clothes from a washer or dryer so that you could use it? (assuming the clothes had completed washing or drying and the owner had just left them there)
Have your clothes ever been removed from a washer or dryer? How did it make you feel?
Any horror stories?
