The reaction of the waitress (as described) is on the waitress, for sure. (I personally think the video may have been hilarious, and I imagine a lot of service workers who heard this story would think so too ) But sometimes one can think about how their actions might lead to someone else overreacting. Hotel employees are people too, and it is hardly surprising that a guest moving themselves to another table after specifically being told they couldn't would irk the employee. And to the extent OP is expressing shock at what a server could have done to their food while they weren't paying attention, perhaps this is a wakeup call... there's the trope of restaurant staff spitting in the food of difficult customers for a reason, after all.

More importantly, the reaction after the incident, including dissatisfaction with the apology received, is on the OP. The references to being titanium and spending a lot of money are curious. If what happened happened, those are irrelevant, of course. And of course, if a guest is not the most polite, that may very well influence the response they get when something goes wrong--particularly how genuine they feel the apology is.

The OP is asking for advice. No one can change what happened, and the OP is unlikely to be satisfied with any outcome. The OP could think about how their actions that seem to have escalated the situation could have been handled differently.
