Hi Davide,
it's great to hear that you love your barista job as much as we do.
I know what you mean when you say you don't get a quiet moment.
To answer your question about the dry cappuccino:
A 'Dry Cappuccino' or 'Cappuccino Dry' is a cappuccino with even more froth or foam as a regular cappuccino. So if someone orders an extra dry cappuccino they want it extra foamy. Less milk, more foam. I had people you just wanted foam without any milk.
I hope this will help you to get even more compliments
Which cafe are you working at?
I will come and say hi the next time I'm in London for a coffee training.
All the best from Sydney!
David
