You know what? No-one will force you to watch street theatre.
No-one will tie you down and make you watch a man dressed either as Freddie Mercury or Prince performing with hoops or on a unicycle.
But it's a kinda magic if you do.
Mario Queen of the Circus would go down as one of the more bizarre acts I've seen at South Bank. Not often to you see a male wearing a modified mankini twirling nipple tassels. It sounds tacky but it wasn't. Still if it's not your cup of tea, walk away. Like I said, you don't have to stay.
But if you hang around, if you laugh and cheer, if you clap and take photographs it is really poor form to slink away when the performance is done without putting your hand in your pocket and at least a few coins in his hat.
If we want a thriving street culture (and I for one do) you have to be prepared to support the street artists.
You don't work for nothing. Why should they. Just be thankful you don't have to wear nipple tassels to work. It's a tough job but someone has to do it.
