I've gotten myself fired for doing this. I kid you not, but they took it as a sign of disinterest and somejow never thought to bring up "yo Martin, what's up with that?" 100% ridiculous childish twattery, but just sayin' ... you can end up in trouble. This was literally the only thing they brought up as "evidence" for my alleged "attitude problem".
(I can foresee "dodged a bullet" responses, so just to pre-empt that: I didn't. I actually enjoyed working there, and being fired led to significant financial troubles, and even greater mental health problems. I got hit by a bullet and didn't dodge anything.)
My contract wasn't renewed; technically it's not really "getting fired", although it doesn't really make that much of a difference in reality. Even if there was a wrongful dismissal case here, I wouldn't want to pursue it – the headache and stress just isn't worth it.
