First experience at a maid café

I guided a Canadian parent and her daughter to Akihabara. Her daughter wanted to go to a maid café, so I took them there. It was the first time for both me and her mother. When I asked them if you would like to come back, her daughter replied that she would like to come as many times as she can, but her mother would probably not. In my case, I was a little confused and couldn't decide which way to go.
