Most customers prefer to use plastic bags but they are prevented from using them on Saturdays as my shop has implemented the "No Plastics Bag on Saturdays".
There is a couple who is very supportive of not using the plastics. Each time they come to my shop, they would definitely refrain from using the plastic bags. They would rather carry the stuff with their bare hands.
I really salute them. Furthermore, they are such nice couple and I have much fun talking to them.
