But to each their own!!!
Anyhoo to answer the question:
For years, I really didnt have one, wanted to see and hear EVERYTHING. Every little note in Minglewood, Rooster, Des Row, CC Rider, Push, Walkin Blues..you name it, I would not miss it. Even Day Job~~~~
Drumz when I could hold no longer...but really it was the intro of songs like
Wave to the Wind & Corrina when I decided...oh man, pee break songs.
“The Omnipotent Grateful Dead!”
Don't get me wrong, I used to dig watching them beat the tar out of the skins, but it was an opportune time in my opinion for a piss and a beer or whatever.
I would often leave for the same reasons during a first-set FOTD, CC Rider, Minglewood, Jack a Roe, Me and My Uncle, Mexicali. Only if need be, mind you.
I (we'd) also leave the show early if Day Job notes were struck for the encore to beat the squeeze out to the lot.
For me, since I started going to shows only in '93... it would be Easy Answers. I've been to a bunch of shows but unfortunately had to see this one too many times. I would probably have to say the same for Eternity and for Way To Go Home.
Black Peter.
Sorry Gans (who gives me shit about that) but I know I'm not alone here! There's a little giggle story about that associated with this year's KPFA GD Marathon.
I think Estimated might have been a pee song sometimes, too. but never, ever out of the hall for Stella Blue, Mexicali Blues, or anything that featured Brent.

Boy, whenever the boys started to drift into Dark Star, I just had to duck out.
IMHO, this question deserves nothing more than such a sarcastic, ridiculous response.
Maybe my view is distorted because I stopped seeing shows in about 1983. Did things get so bad that "just about everybody" had at least one song they despised hearing? I recall there were some songs that I didn't love, and after hearing 40 or 50 "drums," I sometimes got a little bored, but never did me or any of my group of deadheads want to be anyplace else. Wow.
