When i go on my own, there are very few instances i will leave the house without them. Ive never forgotten them in the car, but if i did i would for sure go back and get them, other wise carrying all those groceries becomes too much a chore since i can carry 4-5 bags on each arm at once from my car to the house, unlike pastic bags where i can only carry maybe 3 at a time.
Never! I prefer new and uncontaminated plastic grocery bags from the stores. If there comes a day when all the stores are not allowed to supply plastic grocery bags, I'll buy my own at Costco and use those instead. I always recycle those used plastic bags as garbage bags afterwards, so I still consider myself green.
I'll pay the .10 for the paper bag, make sure they fill it to the top and then use the paper bag for fire starter at home. I refuse to haul bags back and forth. Then I will go home and drink a 32 oz soda, put extra salt on my chips, take an extra long shower and flush my toilet twice.
Yes I am kidding, but I hate to be told what to do.
