Resuming Play

[Dbyb]

I had a JVG game last week where my partner and I came out at 3 minutes left in the intermission. The 3 minutes run down and only one team is on the floor. The refs, timer, scorer, and team "A" are all ready to go but team B is still in the locker room. I know about the resuming play procedure outlined in 7-5-1 but I surely want to avoid putting the ball in play for an uncontested layup, violation, and then a technical with only one team on the floor. Fortunately, within 5 to 10 seconds after we were ready to go, team B sprints onto the court and we start the second half. My question is do the officals have a responsibilty to send someone to get the other team on the floor if they see that this situation could occur? Have any of you had this happen and had to administer penalties with only one team on the floor?
