Like old toilet paper rollers, these devices are capable, (especially if low on bags), of not only unrolling more bags than desired, but of actually leaving their housing to festoon the bags across the floor. The bags themselves are difficult to properly tear off the roll, confusing as to which way is “up”, and challenging indeed to open so that the payload can be inserted.
The photographs below give a hint of this, but you have probably experienced the frustration of trying to use them many times yourself. If not, I would appreciate knowing where you shop.
The first photo shows the bags lying flat (notice lack of marking where you tear them apart).The bags are folded in a strange manner, and the next photo shows what you see as you try to figure out how to open one. The photo after that is an indication of the opening when/if you succeed. How about trying to put a head of lettuce into that confusion of thinner than tissue plastic. And even if you do succeed in opening it, the next photo of the bottom of the fully open bag shows that they are diabolically designed so that the bottom is not obvious.
They are not only functionally a nightmare, they have a sleazy feel, an ugly look, and despite the optimistic note encouraging returning them to the store, probably are not very favorable to the ecology. Also they are so thin that I have a few times succeeded in dropping a purchase through the bottom, which is non-relaxing to other shoppers.
As a positive, they result in the opportunity to meet nice people. I usually shop during the day, when many of the other shoppers seem to be mothers with children who would rather be somewhere else. Today, I got to know a nice lady who had an unhappy child in a stroller and was carrying a baby who was having a temporary meltdown. How about trying to open one of these bags and put produce in it with one hand while trying to calm down a couple of unhappy kids? I helped her with the bags (not the kids) and she was so obviously grateful that it alleviated the anger I had accrued from my own previous bag experience.
Another good piece of news is shown in the last photograph (apple by mirror). Upon reaching home and emptying one of said bags I found that I had won an apple with three of the pesky little labels that you have to either swallow, spit out, or peel off. Wow! Must have been because I am a member of the Safeway club.
