Today, if you were to try and do business while O.C.-ing, you're going to open up a lot of controversy, possibly get fired etc. It draws a lot of attention, mostly negative.
I didn't live 150 years ago but apparently back in the day, it was not unusual to OC/CC all the time.
But today, it is unusual. Should it be? Probably not.
I have no intention of OC-ing but I kind of appreciate those who do. I just hope that it doesn't backfire.
