Why don't they just ask if anyone in your party has a bag, if the party says no then they are released into the rest of the line. If they say yes, the team member says one person please take all the bags to the lockers over there, everyone else wait in this "holding area". As soon as your party is together proceed into the line. I mean they already have the outside line that releases you into the locker area, they could control it better and not scream at people. I did notice the one thing my friend and my sister said about Universal is the team members don't seem as nice and I think it comes from the "screaming" to get people to do what they should do. If they controlled crowds better from the beginning they would probably not have to scream. Like they finally have single rider where they stop you before going in and make sure you know you will be separated. They used to scream it in the line several times and people still didn't listen.
