There are rules and then there are rules: The key scripture they use to justify a rule is 1 Cornithians 14:33.

Indeed, Christians are obligated to observe all commands in the Bible that are directed to followers of Christ. And there is more. Jehovah’s organization, as well as individual congregations, has to establish necessary rules and procedures in order to preserve good order.
(1 Corinthians 14:33, 40) Why, Christians could not even meet together if they had no rules as to when, where, and how to hold such meetings! (Hebrews 10:24, 25) Cooperating with reasonable guidelines laid down by those given authority in the organization is also a part of fulfilling the law of the Christ.—Hebrews 13:17.
Nonetheless, true Christians do not allow their worship to become a meaningless structure of laws (only a meaningful structure of laws). They do not serve Jehovah merely because some individual or organization tells them to do so. Rather, the driving force behind their worship is love. Paul wrote: "The love of the Christ compels us." (2 Corinthians 5:14, footnote)

Those who despise Jehovah’s teaching include individuals who criticize and complain about Jehovah’s clean organization and its rules for maintaining peace and good order.

Some rules are specifically for the congregation’s good. For instance, in the past some Christians could speak in tongues. Paul directed that only two or three of them speak on an occasion, that they take turns, and that a translator be present—rules that promoted peace and order. (1 Corinthians 14:26-33) Similarly, the elders of a congregation today might provide directions about keeping Kingdom Hall exits clear, not saving seats needlessly, or parking vehicles with consideration for neighbors and safety. Such congregational rules are not unscriptural for they have the same purpose (peace and good order) as did Paul’s advice about tongues. Related to this is the Biblical advice: "Be obedient to those who are taking the lead among you." (Hebrews 13:17) Since our avoiding sins such as lying or stealing involves obedience to God, this text must refer to our obeying the elders’ guidance in congregational matters. Nor is it difficult to do so if they are not legislatively "lording it over those who are God’s inheritance."—1 Peter 5:3.
