I moved to Europe in 2018. The banking system is decades more advanced than the US. At least where I am, no restaurant will “split a check” and one person is expected to pay. We settle the bill between each other in a matter of seconds.

Most bills are paid using this exact system. Credit cards are very rarely used except in-person. Since you have to accept (or tell your bank to always accept certain vendors) debits using this system, there’s never any surprises. You usually have nearly a week to accept a debit.
