Get over it, it didn't really hurt your beer.....not every clerk is a beer geek....a half hour in the fridge and it will all settle back down.
I mean jeez, folks make these threads all the time and no one friken thinks about what the bloody car ride back to their home to drink it is going to do to shaking it up....Unless you're going to down it in the parking lot outside the bottleshop in a brown paper bag, you're going to do just as much bleeding shaking....
Sorry, but even micro breweries like rogue and bells put the bar code on the bottom of the 6 pack, even for the bottle conditioned ones...if they were so concerned, you don't think THEY would change that.
Go back to thinking about how hot she is.
