ἀπεπέμφθην ἀτιμότερον ἢ πτωχὸν ὑμῶν ἀποστελλόντων προσήκει καὶ κελευόντων ἐκπλεῦσαι, τοσοῦτον παρ᾽ ὑμῖν διατρίψαντα χρόνον.
I do not understand the Acc ἀτιμότερον unless it is attracted somehow to πτωχὸν which forms a construction of Acc + inf (implied apopemfthai) with προσήκει .
Isn’t it just the comparative adverb? (“I was dismissed more dishonorably than is seemly when you’re sending away a beggar …”)
