Late again

A secretary comes in late for work for the third day in a row, so her boss calls her into his office.

"Look, Sharon," he says irritably. "I know we had a wild fling for a while, but that's over. I expect you to conduct yourself like any other employee around here. Who told you that, just because we had an affair, you could come and go as you please around here?"

Sharon lights up a cigarette and says, "My lawyer."
