The actor is appearing on reality show Famous Food, alongside Heidi Montag and Danielle Staub, and was filming scenes where the stars were drinking glasses of wine.
At the end of the night Pastore asked for his vehicle to be returned to him, but a crewmember refused and demanded he hand his keys over to her.
In a video posted on TMZ.com, the female worker is heard saying, “I cannot bring your car around, give me your keys.”
Pastore then flew into a frenzy as he insisted he hadn’t drunk too much to drive, fuming, “That’s bulls**t guys, that’s bulls**t. You guys didn’t tell me that at 4 o’clock today, OK…
“I purposefully didn’t drink tonight. I poured my wine back into the bucket and I’ve been drinking coffee all night. I need my car tonight. I’ve got things to do in the morning, now don’t start with me… Get me to my car, I’ve got things to do in the morning.”
The website reports the star was eventually given a lift home by a friend.
