If a table is playing really friendly, is it bad etiquette to shove all?

I was playing about a month ago, the table was playing really friendly poker, no one was jamming a bunch of chips into the middle. On this particular hand, I wake up with pocket Kings, I raise 3x bb to $1.50. BB calls. The flop comes 4s 10c Kc. I bet the pot ($3) and BB comes over the top for $6. He's been playing pretty tight, so I put him on AK. I shove all in for the rest of my chips ($74). He has me covered and calls and turns over Ks 4h. The turn and river are blanks, and I take down the pot.
Was that bad etiquette to go after his stack? I play because it's fun, but also to make some money - like everyone else I imagine. The guy was really cool about the beat, said "that's poker" and that he put me on Aces. Anyway, I'd appreciate your thoughts.

Thanks
