Canceled Wedding Hair and Makeup Booking

AITA for canceling the hair and makeup appointments I paid for at my sister's wedding?

I, 24 female, paid two thousand dollars for a professional team for my sister’s

wedding as a gift. The only thing I asked was that since I was paying, I could get my makeup

done first so I could help with the flowers later. On the wedding morning, I arrived and my

sister told me I had to wait until the very end because her "new best friend" needed my slot.

When I complained, my sister told me to "stop being a brat" and that since it was a gift,

I didn’t have a say in the schedule. I didn't argue. I just walked outside, called the coordinator,

and canceled the entire booking. Since it was under my name and my card, they took the cancellation.
