Three separate places I went to at 8 in the morning. Gas station, dunkin' donuts, and then a convenience store. All of them, trash is full. People wonder why they litter in the USA, there's nowhere to throw away trash when you're out. It's unbelievable People can just go to work and choose not to do their job anymore. That people see this and they don't have any problem with it, no interest at all to keep things neat and tidy and clean. Nope.
Or, hear me out... carry it until you find one with room? If finding full trash cans "forces" you to litter, that says more about you being an entitled piece of shit than it does about anything else.
"I couldn't find a single vacant public toilet, so I did what any sensible person would do and took a shit in the middle of the sidewalk." —OP, analogously
