Doubling the service fees from your bank.
Depends on the bank. At my bank if you have a checking account, you can get a basic savings acolytes for free. They also have free transfers between accounts (which is very nice because on the basic savings account you are not allowed and other type of transfer for free).
Your second point about the overdraft fees is again dependent on banks. For mine if you don’t have enough money it will just decline the transaction.
It’s true that this does nothing for credit cards though and the constant transferring on money is rather annoying.
