Sawadee ka!

I am a student doing research on Thailand consumers' bag use.

So I would like to know do people in Thailand usually bring their own shopping bag? Is this trend common?
Or do they still prefer plastic bags provided by the store?

I would greatly appreciated if you can spare some time to help me fill out the questionnaire.

You do not have to be a Thai to fill out. All answers are welcome!

Thank you very much ka!
