Stores like 7/11, AmPm, & Circle K serve hot dogs, pizza, sandwiches, etc. Yet, THERE’S NO PLACE TO EAT THEM AT. You either had to eat them in your car, find a park near by, or be awkward & eat them in a restaurant. Like, if Japan, Korea, the Philippines, or even fucking MEXICO, why can’t the US? Like, are WE THAT FUCKING LAZY?!?!
It’s likely a cultural thing.
For instance all the countries you mentioned with space to eat in are also countries that have universal healthcare. So perhaps, in those other cultures, there is greater empathy for fellow persons and value in service to and hospitality for others.
