Yes. The line is when what is requested becomes immoral. That is the Catholic standard of civil disobedience. Inconvenience, regardless of how great, is never a justification for refusing to submit to lawful authority. I know this is not what one wants to hear, but that is the Catholic moral standard.
But there is also ambiguity here. Am I showing more charity to stay home from my favorite restaurants, or to continue patronizing those restaurants so that the owners and employees can continue to earn a living and pay their bills?
Ideally, we should do “take out” from our favorite restaurants, but many restaurants are just not suited for this kind of dining. I do think that these places should try to think outside their box–perhaps come up with “the Special of the Day” everyday by selecting the Top Ordered items that they sell throughout the year and offering them as takeout meals.
But there’s practical aspects to that, too. How do the waitresses factor into “take out?” And really, how many people really do take out.
Interestingly, my brother does–he stops by his favorite restaurant almost everyday for a meal, and tips big.
And my daughter (the entertainment professional who loves to eat out) does the same, and she is tipping 50% these days to try to help out.
Anyway, I think that people’s motives for continuing to dine out (or inside) are not necessarily “civil disobedience”, but rather, helping their restaurant friends stay afloat, and that’s a good motive.
