Shorter me: bollards.
I was actually just having this conversation last night with a friend of mine. We both have a mutual friend who works at a very large non-profit theater named after a famous president, who she reports could literally not charge for tickets and still have enough money to put on their entire season, but is absolutely terrified to put on anything that might alienate their wealthy donor base.
Whereas my theater company's real problem is expanding into the not young audience, because we're young people who make theater that young people tend to like.
(Updated: And people who say "Young people don't like theater" are basically pretending sketch comedy and improv aren't theater.)
