I left mass during a raffle at the end. Was this sinful?

Some context, I usually go to a 730am mass at this particular church when visiting my dad. I went at 8am completely forgetting it started at 730, so I showed up super late and decided to go to another church instead that had an 8am mass.

I find one, but it’s in Spanish. No problem, so I go in and they give me some ticket, no clue what it is. Whatever, so I decide to stay the entire mass up until announcements.

After about 10 mins of announcements and a presentation, they start a raffle. At this point it’s about 9:15am and I have no clue how long this will last and I’ve got family at my dad’s waiting for me for breakfast. So I leave and as I’m exiting, this gentlemen asks me a bunch of stuff in Spanish, so I just tell him sorry my Spanish isn’t great I was just trying to find a mass. Then I leave.

Turns out we’re not supposed to leave during announcements and should wait till proper dismissal from the priest. It may sound silly, but did I commit a sin here? Not sure if anyone has been in a predicament like this before.
