Absolutely! The shoplifting bit!!!! Being afraid that people will look at you funny, or 'check' you at the door....
Well- as for the trollies, i really can't use one... I live in the sticks, and the closest post-office/shop grocer is 5 min by car, and the closest real-grocer is about 15... So- while the trek would be scenic, it's going to become VERY unseasonable here shortly!
But- I still use reusable cloth bags to put all my groceries in. Anyhow I HATE how you have to pack all your own stuff! The funny thing is, I also used to hate having someone else (who you know is being paid pittance!) do it for me!! There is no happy medium!
But ya, here, I have this system now where as I go through the shop I separate all my items into 'categories'... Fruit/veg, cold/dairy/frozen, dry goods, household products, etc... Then, when I get to the check-out I put it all on the belt in order that I want it to come down so nothing gets crushed, and it's all organized!!! But- i put all my items in my bags, in the cart as I'm shopping too- and I'm always a bit worried someone's gonna stop me one day and assume I'm trying to nick it all!!! Oh well! For now- it's my system and it works like a charm!!
