Lena from the Bosporus told me about this one.
This guy has a hole-in-the-wall pizzeria on the Ludwigstrasse, just around the corner from the Maria Ward school, for girls.
Every afternoon, he's invaded by hordes of nubiles, flashing their eyelids (and I wouldn't want to know what else) and asking for "this extra" and "that extra" on a Pizza Margherita.
Now, a Pizza Margherita is tomato and mozzarella.
I though this guy was a purist, defending the original concept of the Margherita.
"No, mate" he said "They were bankrupting me"
"That's why I put up the sign"*
"Doesn't stop them asking, though..."
*"You can't have the large Pizza Margherita with salami, ham, pepperoni salami or tuna"
