Shit happens. While it might not have been the best idea to drive a couple of feet in your car while you were drunk, what's done is done. I'm sure he learned his lesson, I'm not going to sit here and preach to him.
Props on not trying to get on the streets to drive home or look for a place to sleep. I can understand someone completely sober sideswiping a car/pole in a parking lot because they turned too early while backing out. Heck, it puts me on edge sometimes the way some of my friends pull out of parking spaces. We are more entrained to focus on other cars/ people when checking our surroundings... poles are easy to miss, especially low rusty ones at night
You can get cheap clips at
www.hondaautomotiveparts.com but shipping is like $6-8 so get everything you ever needed for your car before ordering... such as air filters, oil filters etc.
Good luck on the repairs and show us pics when you're done.
