I usually have my own bag. But shops need to be flexible too.Once I had no bag and I bought something that was quite large in size. I was so angry when they told me it's No Bag's day. I was about to leave and not buying it. Then, they gave me a bag.
巔兄,"no bag day"只是呼籲大家別用膠袋,當然如果買大件的東西,而又無帶袋的話,商店最好要提供膠袋了,現在是"交接期",無膠袋日是一個好的開始,只要慢慢進行,讓市民漸漸習慣都是好的,但要看個別情況就更加好了!
