Joan, a flat white should be just that -a flat white, just a little tight froth on top, just enough to keep it civilised.
Problem is, very few kids who work on coffee shops nowadays actually DRINK coffee (think back to when you were a kid - did you drink coffee? I didn't start until my mid twenties).
I trained as a barista a few years ago, just because the course was cheap and I was bored out of my skull. The guy who trained me told me that there was virtually no difference between a flat white, a latte and a capuccino, same amount of coffee, made in exactly the same way, the difference was in the frothy milk. Just stick chocolate powder on top for capuccino or chocolate powder in the mix for a mocha.
Coffee shops are a licence to print money nowadays, and I resent paying the money for some snooty young dweeb to patronize me.
I do have an espresso machine at home, by the way, and I use it occasionally but there's no substitute for the McGookin system if you have a number of coffee-loving guests who all want to be served quickly. I can make up to ten coffees at a time in one go, and very quickly.
