Ours is not just a dry paper bin, we throw rotten food, meat, bones, and dirty diapers in it. It's definitely fucking disgusting. I'm not taking the lid off and having an open air stinky garbage can, that's also disgusting. We do wipe it down on a regular basis, especially when people are coming over because no one seems to think trash is dirty and shouldn't be touched. However I never see other people wipe their own trash down. I do frequently see them open the lid, remove the bag and take it to the outside trash or dumpster, then come in and replace the bag and shut the lid, then immediately move on to touching food, etc without touching their hands. I know the outside trash cans and dumpsters are dirty because there are varmints and bird shit other visible gross stuff on it all the time which they just transferred to their inside can/fridge/everything in their house. My family is objectively disgusting and I was never raised to wash after touching the garbage, but I always thought it was gross and wanted to wash after handling garbage. I thought my family was just a bunch of animals, but from all the people in my extended family, neighbors, wife's family, friends, coworkers, etc I have never witnessed anyone with the same mindset as me, with the exception of my wife.
Sometimes I do think I am a little OCD and germophobic by comparison to other people, even though it just seems like common sense and good practice to me. Wash your hands after touching garbage cans or toilets. Wash your hands after touching public door handles. Wipe your own door handles, phone, and remotes down on a semi-regular basis to not spread gross germs around. I know I'm probably not going to get sick if I touch my indoor trash can lid and don't wash my hands, but it still grosses me out. But other times it just seems so clear cut to me that it's disgusting, like when a friend will help out by taking the trash out either while smoking a cigarette or immediately preceding smoking a cigarette (cigarettes being disgusting is a separate discussion). I mean it's full of rotting trash, I can smell it, it smells like gross trash. There are scuff marks and chew marks from animals (probably rats, raccoons, etc) trying to get into it. I've seen maggots in that trash. I've thrown dog shit in that trash can, while lugging it around the yard cleaning up dog shit. To handle it and then touch your lips while smoking is the equivalent to just putting your lips straight on it.
I'm glad to see some of yall on the same page as me, because with the exception of my wife I am like 0 for 100 in observations with everyone I know. No one seems to be bothered by touching trash cans. I also know a fair number of people that don't wash after using the restroom. Most do though, but they don't seem to have a problem touching things in the bathroom as long as they aren't actually going to the bathroom. Like they will go in and open the toilet and flush a kleenex, and not wash since they didn't actually go to the bathroom.
