If you happen to be in Nice any time soon, go to La Petite Syrah for a drink. But not if you’re feeling grumpy – the price of a coffee is 7 Euros if you just demand ‘un cafe’. However, if you say ‘please’,  it will only cost 4.25 Euros. And if you are friendly as well as polite, and say ‘bonjour’ as well as ‘s’il vous plait’ – well, you’ll be charged only 1.40 Euros.
