Cameron goes back to bar - and this time he leaves a tip
Earlier in his holiday, the Prime Minister paid a €3.10 (2.70) bill with a €50 note and failed to leave any small change as a tip, as is customary in Italian bars.
Last week, waitress Francesca Ariani, 27, failed to recognise Mr Cameron when he walked in with wife Samantha and ordered two cappuccinos, asking for them to be taken to an outside table. Ms Ariani told him she was too busy and that he should serve himself.
Mr Cameron returned with his daughter Nancy to clear up the misunderstanding at the Dolcenero bar in Monetvarchi near Arezzo yesterday. He ordered a beer for himself and a soft drink for Nancy - paying the €5.10 bill with a €10 note and telling her to keep the change as she served him at a table.
Ms Ariani even offered the Prime Minister a cocktail she had created - the "Cameron Tuscan Dream" - with the ingredients being local vin santo (sweet wine), coffee and cream.
She said: "I was so surprised when he came back to the bar after what had happened last week. I said I was sorry for not recognising him and not serving him, and he said it was not a problem.
"He said he was sorry for any fuss that had been created and he was very nice, very friendly. He ordered a beer and a Sprite for his daughter Nancy, and I took them out to the same table where he was sat last time."
The 16-bedroom villa where the Camerons are staying is on the Petrolo wine estate and in addition to the main house, there are four smaller properties, one of which has been taken by Mr Cameron's security team.
It is close to the hamlet of Bucine in the Tuscany region known as Chianti, which is popular with British holidaymakers, many of whom have homes in the area. Sting and his wife Trudie Styler are close by.
Chef Jamie Oliver is a close friend of Petrolo's owner, Luca Sanjust, and visits every year with a team of his students to watch the olives being pressed and turned into oil.
The coalition government has been heavily criticised for having Mr Cameron, Deputy Prime Minister Nick Clegg and Chancellor George Osborne all on holiday at the same time, while the world's financial markets are in turmoil.
