Sometimes and I say sometimes we get a little fed up being kept in the dark or even straight up lied to by ground staff. Then we get a little vocal.
I love it when we do stand up for what is right then later get blamed for the delay!! On more than one occasion I've had to use the ACARS OOOI times to prove my point in correspondence where they tried blaming the crew for a delay.
So don't blame us for getting a little cranky every now and then.
