You're not getting off that easily, Cyan.

Sure I am. If you want to front the "unemployment compensation package", go ahead and run your own experiment.

To the extent that they don't expect a tip, they may still bring out the food, but not with the same effort and enthusiasm.

...or sabotage the food while I'm not looking. No duh. I'm just saying that I expect they wouldn't refuse to serve me outright.
