Was this mother in the wrong? Or the Shop?

I'm very curious to see others opinions. 
The other day a mother who was dressed lovely and conservative brought her very young children who looked like they were under 5 into a clothing store which sells quite revealing clothes. It's a store that sells clubbing clothes and some crop tops shorts and other little clothes. The age group is for young people. 
Anyways, the store plays the latest music that they are playing in the night clubs. 
The mother walked in passing majority of the racks with her children and yelled very rudely at the sales lady to switch the music off because of the derogatory language. 
To be quite honest I thought, why bring your children into such a store practically lingerie in here with your children obviously your not going to buy anything. But then I thought, I would've done the same thing if I was with my young children. 
What do you think?
