Something Smells
We all realize that public transportation isn’t entirely clean, and we understand it. But this is just inconsiderate. We try our best to avoid touching anything or grasping the handhold during the bumpy journey, but there’s nothing we can do when our hands inevitably touch something or grasp the handhold for support. So at the very least, I’d hope he didn’t have an awful fish-like odor (not to mention how greasy this handle most likely was after his use).
Forget about the other people on the bus, carrying their fish in a bag, wearing no gloves or anything else to keep them separate from the outside environment. It doesn’t seem very sanitary to eat this fish, knowing how it has been handled. This individual, on the other hand, does not appear to mind.
