Fuck convenience store clerks who don't understand how plastic bags work!
I'm at the corner store buying something heavy that I've bought 100 times before, and I've learned that it's heavy enough that it will sometimes tear through a single plastic bag on my two-block walk home from the store. So, I normally ask for a double-bag.
Well, they put my items in one plastic bag, then someone else walks up to help the clerk double-bag and pulls a second bag (from about 12 inches to the right of where the first bag came from behind the counter), and puts it over the first. Well, the second bag is smaller, with the handles about three inches shorter than the first bag, and then they hand it to me to leave.
I look at them confused, and ask for a second bag the same size as the first, because in it's current state that's still one bag holding the total weight of the contents...till it breaks, then the inside single bag will holding the weight by itself as well. This defeats the purpose of asking for a double bag.
Next, and I shit you not, the clerk looks me in the eye and says "but, it's still two bags!?!?", and just keeps staring me dead in the eye as if I'm being an asshole about it.
At that moment, inside my head, I thought about grabbing that dumb fucker by the throat and pulling them as close as possible over the counter to my face, and screaming at the top of my lungs (flying spittle and all) "that's not how physics works, you dumb fuck!"...but I don't like police. So I took my bag and left.
Of course on the way home the handles of the smaller bag slowly stretched to wire-thin, starting to get painful as they cut into my hands and one of them broke, so I switched to the other handles of the larger inside bag, which was beginning to tear at the bottom by time I got home.
I guess I'm ultra annoyed because this has happened many times at local convenience stores where I ask for a double bag because I know the contents are a bit too heavy for one bag, and the inside and outside bags they use are different sizes, and they always look at me like deers-in-headlights when I point out that there's a problem with that.
Why is this aspect of plastic-grocery-bag mechanics so hard to comprehend for some people?
