Do all banks charge a service fee?

Excuse me, could you clarify for me if it's a universal practice for all banks to levy a service fee on their customers? I've noticed that some banks have mentioned fees in their terms and conditions, but I'm wondering if there's a standard across the board, or if it's more of a case-by-case basis depending on the bank's policies and the specific services being offered. Additionally, are there any banks that operate without any service fees at all? I'd appreciate your insights on this matter.
