would you be pissed?

so my fil is a dj not a very good one at that. well for me and my husband's wedding fil wanted to dj we said ok it's save us money. well we wanted our and bridesmaid and groomsmen table to be on the stage. his dad through a fit saying I'm not gonna be on the ground where kids can mess with my stuff. he threatened to pull out of our wedding 2 DAYS before the wedding!!! so no choice we say ok you can have the stage. well half way through our wedding his computer breaks down over headed because he didn't have the proper stuff for it. so for the rest of the wedding he is using his phone to play the music. not even music off our playlist. I was pissed but didn't say anything. but still would you be pissed?
