Agree.
Churches are terrible markets.
My own had a problem with the software they used for projection. Sometimes the copyright wouldn't show up, and transitions between song sections could take between 1 and 2 seconds, meaning that the projectionist had to be pre-emptive, but worship leaders often change what they're doing on the spot.
I dug into the product, and found that the bottleneck/inconsistencies was the database - a Borland database.
I interviewed and sat through the same crap meeting schedule and many, many last minute cancellations, but got a product that was faster, kept the legal requirements better, and was easier for the projectionists to use.
But, the Church refused to buy it for more than a single $5 fee.
They had spent $20 on the old software 10 years ago.
I was told that there wasn't room in the budget for the $50 I was asking, despite quoting that when I started working on it with them a year before.
I was so annoyed that I did something I've never done before: I deleted the code I wrote.
