    _call: &T::Call,
    _info: &DispatchInfoOf<T::Call>,
    fee: Self::Balance,
    _tip: Self::Balance
) -> Result<Self::LiquidityInfo, TransactionValidityError>

Withdraw the predicted fee from the transaction origin.

Note: The fee already includes the tip.

fn correct_and_deposit_fee(
    who: &T::AccountId,
    _dispatch_info: &DispatchInfoOf<T::Call>,
    _post_info: &PostDispatchInfoOf<T::Call>,
    corrected_fee: Self::Balance,
    tip: Self::Balance,
    already_withdrawn: Self::LiquidityInfo
) -> Result<(), TransactionValidityError>

Since the predicted fee might have been too high, parts of the fee may be refunded.

Note: The fee already includes the tip.
