You're working in a restaurant that closes at midnight, and at 11 a bunch of people arrive and want a table. And you say: We close at midnight, so you can obviously sit down now but I want to be clear that I would like you to be gone at closing time. They act offended that you would even imply that they might be planning to take advantage of you, like of course not, they're going to leave at midnight, they really mean it. Midnight strikes, 12:30, 1 a.m. and you're standing near the table with your eyebrows basically rolling off the top of your head and they're still there, ignoring you, nursing their last beers, laughing at their own witticisms. When they finally leave, they don't tip.
How many times do you let this happen with that group before you stop trusting them? How does it affect your attitude toward another group? At what point in your story do you refuse to let people drive over you? What if they personally haven't done anything to you yet? Why, in this story, does it feel to you like telling them to leave makes you the bad guy? Why, when telling this story, do people act like if you fail to fight back there's something wrong with you? What about if this is not a job at a restaurant and customers and closing time, but your house, your friends, your bedtime? What if it's mine?
