No, your point was not lost; in fact, what you said is exactly what's so grating about "guilt tipping."
Think of it in terms of privacy. Whether I can afford to pay $1 or $5 or $50 for a cup of coffee is none of your business. I don't care if I'm destitute or a serial Powerball winner.
Suppose you stood next to a Starbucks cash register. As each person reaches the front of the line, you announce "you look like the kind of person who can pay more," or "yikes, you can barely afford that lemon-twist chai, here let me press the no-tip button for you." Can you imagine how you are making those people feel? No customer wins in that scenario.
Yes, buying coffee should be "trivial." Now it's been elevated, by design, to a public shaming.
