Try not to be so sensitive. The 'hogwash' was for the crew.
By the way, you said
"They had selected flaps after engine 1 start" which is NOT normal procedure. I said "before engine start is complete" and as you no doubt know there are two engines on a 737.
"The fact that the crew did not know they had not deployed immediately after selection was why they called maintenance afterwards!" They should have returned to stand. If flaps do not deploy normally the aircraft is u/s for flight.
So, "my friend" - in my opinion you were given a bucket of hogwash. Simples. The only conclusion I can draw from YOUR story is that they either forgot or delayed it for some reason.
