A devotee who faithfully engages in the worship of the Deity in the temple but does not behave properly toward other devotees or people in general is called a prākṛta-bhakta, a materialistic devotee, and is considered to be in the lowest position.
Srimad Bhagavata Purana

अर्चायामेव हरये पूजां यः श्रद्धयेहते । न तद्भक्तेषु चान्येषु स भक्तः प्राकृतः स्मृतः
arcāyāmeva haraye pūjāṃ yaḥ śraddhayehate | na tadbhakteṣu cānyeṣu sa bhaktaḥ prākṛtaḥ smṛtaḥ
