The venue is a great place for a concert or a show. However, while I understand you can't bring a bottle of water to a concert, bringing it to a kids show should never be a problem, yet they still ask you to throw away the cap. A little flexibility would be appropriate.
Also, having 4.5 coins as a standard (instead of, say, 4 or 5) is really weird, especially since there aren't many things you can buy with a X.5 value. Clearly this is purely aimed at making a profit.
