Peter asked a clarifying question. He wanted to know if Jesus was aiming His warnings to be ready at the disciples alone or at the disciples and the crowd that was present and listening ( Luke 12:1). [source][source][source]
Context Summary
Luke 12:35-48 - Ever On The Watch
The Lord leads our thoughts on to His advent, when He will call His servants to account. The day may pass into the evening, the evening into the night, and the night may even begin to wear away to the morning, but the faithful servants keep their watch. Their loins are girt to serve, and the house is radiant with their trimmed lights. Presently He comes, and He raises His slaves to sit at His table! They are henceforth His friends-and His highly honored friends-whom He serves with His own hands. The grandeur of the reward seems to have been too much for Peter to grasp, Luke 12:41. Surely it couldn't be for all. Yes, said our Lord in effect, to all who are faithful to their possibilities and use their position and gifts for others.
How abrupt and awful the contrast in Luke 12:45-48! The greater our responsibility, the greater our condemnation, if we fail. Retribution is the inevitable penalty of infidelity to trust; but it will be precisely proportioned to our knowledge of the Lord's will. There are degrees or grades in retribution as in glory.

Chapter Summary: Luke 12
1Jesus preaches to his apostles to avoid hypocrisy 13and warns against covetousness, by the parable of the man who set up greater barns 22We must not worry about earthly things, 31but seek the kingdom of God; 33give alms; 35be ready at a knock to open to our Lord whensoever he comes 41Jesus' disciples are to see to their charges, 49and look for persecution 54The people must take this time of grace; 57because it is a fearful thing to die without reconciliation
Greek Commentary for Luke 12:41
Peter said [Ειπεν δε ο Πετρος] This whole paragraph from verse 22-40 had been addressed directly to the disciples. Hence it is not surprising to find Peter putting in a question. This incident confirms also the impression that Luke is giving actual historical data in the environment of these discourses. He is certain that the Twelve are meant, but he desires to know if others are included, for he had spoken to the multitude in Luke 12:13-21. Recall Mark 13:37. This interruption is somewhat like that on the Mount of Transfiguration (Luke 9:33) and is characteristic of Peter. Was it the magnificent promise in Luke 12:37 that stirred Peter‘s impulsiveness? It is certainly more than a literary device of Luke. Peter‘s question draws out a parabolic reply by Jesus (Luke 12:42). [source]
