Fans who attended the Bruno Mars concert over the weekend were required to put their cell phones into YONDR pouches over the weekend.
The singer told the audience that he wanted them to enjoy the experience and not be focused on their phones. Mars was performing at The Park Theater.
It's become a more and more common practice at concerts.
The pouches are already in use in the Clark County School District. Teachers are using them to prevent students from being distracted in their classrooms.
The reactions to the rule were mixed on social media.
Bruno, your movement against cell phones in your shows is generating a lot of revolt among the fans! Why did you decide to do this in Vegas? Any surprise recordings for us?

@BrunoMars gotta have a word with ya I understand you want to restrict phones during you're shows but it also ain't fair only vegas people can see those beautiful cover songs can't you put at least 1 prof cameraman and only film the coversongs and put them on you're youtube ?

Just saw @BrunoMars tonight in Vegas.... No phones allowed! It was awesome to enjoy the moment and a bummer to not capture some cool moments.
Great concert Bruno
