Plastic bags

I'm very proud of my flatmates: they are folding their plastic bags nowadays and our drawer is super organized.

But why do we have so many plastic bags? I'll tell you: Today I went to a supermarket and bought bread (that was in a bag), a shampoo and three bananas. I went to Froiz (a Spanish supermarket) and there the plastic bags are for free. The cashier put the bag of bread in one plastic bag, and the shampoo and the bananas in another one. The most ridiculous thing I saw for ages!! I wish the plastic bags were banned, at least these stupid small ones that break so easily that you can just put a couple of products in one. gnaah.
