Everyone's experience at Allegiant varies. I can tell you, in my experience, I have had dispatchers argue with me about adding fuel. I've also had dispatchers yell at me for not flying to an airport where the landing distance exceeded the length of the runway, due to snow and ice. I've had them route me right down the middle of hurricanes and tropical storms.
I've had maintenance control tell me to pull the calls circuit breaker on an MD-80 to make an erroneous takeoff config go away. I've also had them try to talk me in to flying a plane back to base because the contract mechanic was several hours away. If you put your foot down and say no, they will finally stop trying to talk you in to doing things.
Just on a side note, my personal record for MEL's on one plane was 26, and the most write ups I ever did on one plane was 16, but that one just came out of a heavy check. Of course the local mechanics said my write ups were in addition to the 50 or 60 other things they already knew about that needed to be fixed. No one told us about those.
But remember, your experience may be different, and your mileage may vary.
