In general, it's not a good idea to talk poorly about your employer in public if you want to keep your job; I've heard of at least a couple cases where someone was fired for "mouthing-off" to their spouse in a public place like a grocery store.
I liked Mikkeller for this, but it got too loud. Irish Bank was also good, slower but quieter. I used to nag my friends about opsec... back when you could go places with friends :*(
