Disagreement with Crew Partner

[Kansas Ref]

Sitch:
A1 is smallish frame guard; B1 is a heavy set post player--prolly outweighs her by 50 pounds. First quarter action--A1 was dribbling down lane, B1 closes down in help-defense mode and established LGP, A1 drives with shoulder into B1 and A1 falls backwards [actually bounces off B1's torso] lands on her hinny while holding the ball. B1 was not displaced much at all. I am in the L position, and whistle with open-hand up, I did pause a half-a-beat to mentally digest the sitch before calling a travel on A1. Then, Partner comes running in with a whistle and calls a block on B1 (in a rather animated fashion).

Here is happened between us: we spoke off to the side [for what seemed like a long time but was prolly only 10 seconds or so] and I told partner that this was my PCA and I had a travel; he then said that “we have to call something because there's a body on the floor". He then added, "trust me, I've been officiating for 17 years and this is how it is handled in order to keep the drama down." I then told him that "I had the call in my primary and we are going with a travel." Admittedly, I believe he felt as though I was not respecting his “17 years of tenure” so to speak because he was 'short' with me the rest of the game and was not as chummy during intermission—or maybe he just continued to hold the belief that I made with wrong call. I bring this issue up to not necessarily debate the ‘correctness of the call’ but to illustrate how we as officials might become suspect to irrational decisions due to the influence of another official who may try to cite their ‘’years of service’’ as a means of justifying the correctness of their call versus relying on the directives from the Officials Manual.
