Note to all people who struggle with opening carrier bags:
Breathe on your thumb & index finger of right/left hand (choose as appropriate) then place said thumb & finger on either side of the carrier bag opening and rub together, thereby opening the bag up.
If it doesn’t work first time try it again, this time hastening the moving of your hand from mouth to bag.
If it still doesn’t work then I’m guessing you have an IQ of two or there about.
