When you state you have 'no filter' that indicates you say whatever is on your mind, this is not a chactertistic which serverves anyone well...unless, of course, the only thing on ones' mind is cute puppies and pretty rainbows.
Levity aside I was once fired from a clinic job when a particularly unpleasant and never happy (that I could ascertain) after I uttered a curse word; the clinic was not open yet, she and I were only staff there. She freaked running to nearest phone to advise manager of my curse word. Well, when manager arrived she told me "FIRED" and had me sit in a corner, I wasnted my clipboard and they told me it was to be collected by another...so freaked out were they I was tempted to say "I probably shouldn't have brought the gun collection in either (this was decades ago but still I could see levity would not be appreciated.) It was treated as if I had something under that tiny clipboard...
Ironically I almost never curse anywhere! Just no filter that day after RN unpleasant went with one to many blah, blah, blah, blah, blah...about something until I'd stated "how the %$# was I supposed to know this?" My colleague told manager she'd never heard that word causing me to wonder how she knew it.
