Before you push back on a rule, find out why it exists. Half the time the reason changes your argument.

Rules usually come from something that went wrong once, and the story gets lost while the rule stays. Knowing the original reason tells you whether you are arguing against caution that is still needed or against a habit nobody has reviewed in years. It also changes what you can say, because you can address the actual worry instead.

Ask whoever enforces it why it is there, in a genuinely curious tone rather than a challenging one. People often tell you more than you expected. Then make your case as a way of solving their original problem differently, which is much harder to refuse.
