Normally I'm not a fan of strawberry shortcake desserts, but the one at HDDR is actually really good, OP. (In case some of the rude comments on here have persuaded you not to ask, which I hope is NOT the case. There's never anything wrong with a polite request. That's totally different than an entitled tantrum.) And if you do ask, and they say 'no we can't sub,' which is not going to happen btw, but let's just play along for a moment, I think I would request then that they not bring it to you (if the whole table is in agreement). You're right that it would be a shame for it to go to waste.
