Where there's a name there's a price.

You may still get away with asking for a free small cup of warm milk for your baby/child/teenager?, you may even skim right on the edge by uttering 'frothy' somewhere along that sentence, yet as soon as you mention the word 'Babychino', (which nowadays seems to have become the official name for a small cup of warm frothy milk), a price tag will instantly be slapped onto your bill alongside your latte and muffin. (The guys at the Children's Cafe have obviously caught on)
It may be only 50p, but as we all perfectly know the ways of inflation, that price will only rise!
That's like SO capitalist!
