Im only guessing, but over time I have observed that yours and K99's posts occur when a particular shift is on duty.
Not that there is anything wrong with adding to and assisiting this forum with your knowlegde and experience, but I for one pick up on the often snarly and sarcastic comments, and im assuming others do to. (Not saying that all of them are by any means... )
A little professionalism is all that could be asked for.
Stay safe.
All I can say is this:
Dang straight i'm sarcastic and snarly. And yep I reackon others would pick it too, so don't think its just you being all ultra sensitive, coz its not
And as to the question of what shift i'm on, well it goes like this, am I even a paid firefighter, I can't ever actually recall stating whether i'm a full time firey or vollie, so i'll just let you keep guessing.
