Jeff Bezos of Amazon is angry with a much -praised theater show in London

Four days after the execution, Bond and Lloyd e-mailed volunteers who performed that evening to “approach the production to keep the experience open to everyone, even if it has high-profile figures.”

The message said: “Bum Bum train is built on empathy. We have seen how experiencing the show can influence meaningful change, even in the most unlikely passengers.”

Others present who have raised eyebrows include Joshua Kushner, The American billionaire venture capitalist whose brother Jared is President Trump’s son -in -law.

The dependence on the show of volunteers has long been a source of controversy, with the UK Actors’ Union Equity against practice.

The makers, who organized the show for the first time in 2004, only recently started taking on a wage from the company, in addition to around 20 production staff.

They have also been open about how the sale of more expensive tickets to private buyers compensates for the costs of public tickets, which they estimate would each cost $ 8,000 without the use of volunteers.
