We just did this on May 14 at LTT (party of 8 all on the DP)
We were on the DP and I'd special ordered a b-day cake for my mother in law. The cake was brought out & we sang and ate it. The next day I thought, "Hmmm, no one asked us if anyone wanted our regular dessert".
I didn't really matter because we were all tooooo full anyway.
As nice as our server was, I'm sure she would've brought out dessert for any of who would've requested it. We didn't think about it, & she didn't offer.
***We had way too much cake and left the uneaten half with the family at the next table. They had 3 kids who were eyeing ours the entire time.
