I know this is commonplace but it's so annoying. Yesterday I bought an ice cream and should have received 2 euros change. The receipt (needed to show to get the ice cream) was put on top of the change. I quickly tipped the change into my purse to go and take the receipt to get the ice cream. I realised immediately that the coin I tipped into my purse was not a 2euro coin. I think probably a 20 cent instead. Too late!
As it was I then decided not to stay and do some shopping and have lunch in Rome and went directly to the airport. Rome traders received no more money from me that day and I left Rome annoyed both with the shop and myself for failing for it. I visit Italy about 6 times a year so should know better.
The cafe? Bar Gusto Napoli, via Daniele Manin 5A/7. It's across the road for Termini.
