Either totally boycott the place - permanently (apology or not) - or, fill it with Red MAGA hats and conservatives...order a small salad...be a pain in the ass to the wait/management staff, and then leave without leaving a tip.
ABSOLUTELY DO NOT DO THAT. That is asshole behavior and would make conservatives look bad.
Simply boycott the establishment.
Get with a large group and once you get your order everyone pulls out their MAGA caps. If you’re asked to leave they’re out a lot of money. Let’s see if they’re really willing to sacrifice for their cause.
“and then leave without leaving a tip.”
also, do not under any circumstance actually eat or drink anything served to you ...
