Haha, historically Americans over-regulated their banking system, and got rewarded with frequent banking crises in return. (And America was the only major economy with that problem.)

Eg until a few decades ago many American states banned banks from having more than one branch.

See also the big struggles Walmart had in trying to become a bank; and conversely see how US banks are (or at least were) banned from serving their customers coffee..

It is definite past tense. Donut and coffee Sundays at a local bank are a thing.
