Over Her Green Head

This is a short story.

I went to Target today. I forgot my cloth bags, so I had to take their plastic bags since I had too much to carry in my hands. I thought about going home to get the bags, but that negates the purpose since I'd be wasting gas doing that.

I asked the cashier to just combine the bags since she had made my green heart palpitate by double bagging everything and placing only a couple items in each. She obliged by combining everything into 3 double bags. But then...

She threw the bags I didn't want in the trash. In the trash. In the trash. In my mind, I thought she'd use them for the next customer.

I took a deep breath, picked up my heavy, over-stuffed bags and walked towards the door.

What would you have done?
