I don't want to drip feed but there's quite a bit of backstory on this.
A few years back I was doing volunteer work for an event, I ended up resigning my position because I felt overworked and was having organization-related clashes with other committee members. Since then friends of mine have started working for this event and I've been asked (dare I say begged) to come back on a more casual basis. I agreed so I could help out my friends.
One of the committee members was in charge of organizing a fundraiser, I knew nothing about it until a committee friend messaged me two days before begging me to come and perform. It was supposed to have been a music evening but the organizer had left everything to the last minute and his acts dropped out. I was asked to fill in, as was another good friend of mine.
I dabble in stand-up comedy, which is what I was asked to do. I'm not a traditional joke-teller, I mostly tell stories about experiences I've had and usually my work is a bit raw (my specialty is dressing very prim and proper and then saying terrible things, sort of Christopher Titus-style: I've performed at several events and the organizers have seen and are familiar with my work. With only a day to prepare material I asked if I was able to talk freely, and was told as long as everyone at the event was over 18, it was fine.
So I travelled across two counties to do this favour, it turns out the event is taking place in a church for some reason. The organizer is warming up with two other acts he managed to get, and as much as I hate to criticize someone else's performance as I know how hard it is, it is painfully thrown together. One of the singers is very off key, the guitar player keeps missing chords and apologizing to the attendees (there are only 15 but they did pay to see this) and while the second singer is very good, the guitar player is accompanying her and seems to be playing a totally different song.
So I go on next and start up my act, and before I went on it was confirmed that I could speak freely. Halfway through one of the organizers, who happens to be the head committee member, starts freaking out, waving his arms at me and making the cut-throat gesture. It's very distracting, so I end up cutting my act short and thinking of jokes at the last minute to end on a cohesive note.
The event ends, and the attendees were clearly happy with my performance, as well as my friend who went on after me and did an amazing job. I am told by the committee member who asked me in the first place that we saved the event. But as I'm leaving, the head starts shouting at me, asking me 'What's wrong with you? This is a CHURCH!' I tried to explain that I had been told I could speak freely, but he just keep shouting 'It's a church! Have you no respect?' He could clearly be heard from outside by the leaving attendees. I just told him I wouldn't discuss it with him and walked away.
I'm still fuming. I didn't travel all that way to be shouted at.
