Who needs time? He came down to the plate ranting and raving. He'd be gone before reaching me. Teenager, adult, whatever. Ejection is effective at the end of playing action. Besides, in high enough level baseball, I'm happy to call time after a walk before watching everyone advance a base.
You're not serious, you kill the ball on walks?
