Sensitive husbands don't like second billing.
Thrice happy's the wooing that's not long adoing. So much time is saved in the billing and cooing.
I mean, when I started out I was billing per hour, like a shrink because you would sit with somebody and work. But most of it, if it's for a live show it's usually a buy-out. A flat fee.
From the law firm's perspective, billing by the hour has a certain appeal: it shifts risk from the firm to the client in case the work takes longer than expected. But from a client's perspective, it doesn't work so well. It gives lawyers an incentive to overstaff and to overresearch cases.
Billing and cooing to me is worse to witness an execution.
