I’m a chef. Sometimes I need to raise my voice at staff. Sometimes I need to be harsh and make snap decisions in the heat of service. I not always a nice guy then, but I have to be for my job. But when I get off, of when it’s calm in the restaurant I’m not at all like that. It’s been years since I’ve yelled outside of my job. Having to “play” someone I’m not to keep the place running is tiring and when I’m done I don’t want anything to do with that for the rest of the day.
I imagine it’s the same way for actors. After a long day of playing the bad guy, I can totally see you want to be anything but that afterwards. Though, if you’re an asshole to begin with, you’ll be an asshole no matter what.
P.s. Don’t go thinking I’m some sort of bully chef, last time I actually had to get mad and yell at someone at my job is when an intern tried to open a plastic jar by pointing a blade directly at their stomach.
