Margot Finch goes out to eat. A lot. Like, way too much. Birthdays, Fridays, random Wednesdays — she always finds a reason. And every time, the same thing happens: everyone at the table does their own math, puts their money in the middle, and walks out like everything is fine.

It is never fine.

The waiter always catches her at the door. Every. Single. Time. "Hey, we're still a little short." And because Margot cannot handle the embarrassment, she pays the difference. But here's the thing — paying the difference also makes her anxious. Now she's the one who paid more than everyone else, and that's awkward too. She replays the moment in her head the whole ride home.

And then one night she got home and realized the group had left the waiter zero tip. Zero pesos. The guy had been running back and forth all night. She thought about it for four days straight.

Look — Margot knows tips are not mandatory. She knows waiters should just earn a decent salary. She agrees! But her anxiety does not care about labor policy. If she doesn't leave at least 10%, she will think about it for the next three days.

So now she wants a program. Something she can check before anyone stands up from the table. Something that tells her: are we good, or is this about to be a whole thing?
