Replying to Filming frustration?

I don't film, but my friends usually want to film me and I have solid tricks, but not great consistency. I feel like after I don't land anything worth using for a while, they might get annoyed and have a bad mentality about filming more throughout the day. This has caused me to turn them down from filming me from the day on some occasions.

For the people who actually film, what does it take for you to get tired of filming someone who isn't consistent/not getting the tricks you want to see, not landing anything/or just not up to your standards of skill?

I don't want to make this sound like I am 12, but I just want to hear what other people think about it.
