Oh. That's impressive. People must like their burgers.

In any case, I don't mention the whole pariah thing for no reason. To put it one way, imagine for a moment, being habitually involved with something that's so trigger-ready to outcast you that it will take the words about you by someone who was given the boot from the community as gospel, despite the fact that, along with being demonstrably and chronically wrong, actually arise from an attempt at being tolerant despite you being painted as anything else. Then ask yourself what you've been through that is closest to that, and think of whether that warrants a tip. I for one tip waiters and waitresses for their friendliness.
