Has Pennsylvania seceded?

Celebrating a friend's birthday last night with some karaoke entertainment at a local bar, I won a free drink late in the proceedings by knowing that Strawberry Alarm Clock was the name of the group that had recorded the 1960s hit "Incense and Peppermints."
According to the coupon handed to me by the karaoke host, I could redeem it for a domestic bottle of beer, a rail drink, or a 16 oz. tap. I went to the bar and asked for a Rolling Rock.
The bartender advised me that it wasn't domestic.
I returned to my table with a bottle of Miller Lite, which was a fair 2nd choice, but I had to ask the other people at my table whether Pennsylvania had seceded from the Union without my knowledge (Rolling Rock having gotten its start in Latrobe, Pa.).
I figured that maybe it was a commonwealth issue, which if I'm not mistaken, would have also precluded me from redeeming my free drink coupon for anything brewed in Virginia.
Later, the bartender admitted that it was simply a cost issue (Rolling Rock being priced higher for the bar than other domestic labels).
For the record, I began singing before 9 p.m., and didn't stop until after midnight. There were very few other singers in the regular rotation, so I took the mike 8 times - in order - "Ants Marching," Dave Matthews Band; "One Thing Leads to Another," The Fixx; "The Impression That I Get," Mighty Mighty Bosstones; "You'll Accompany Me," Bob Seger; "Moondance," Van Morrison; "10th Avenue Freezeout," Bruce Springsteen; "Lady (You Bring Me Up)," the Commodores (w/ Lionel Richie); "And She Was," Talking Heads.
"You'll Accompany Me" and "10th Avenue Freezeout" I was trying for the first time.
I've got some Dos Equis Amber in the fridge at home right now; now I know that's not domestic.
