A customer left a one star review on Trip Advisor after a bar in Italy charged them €2 (£1.72) to serve a toasted sandwich on two plates.

The disgruntled visitor, who was with a friend, ordered the snack at Bar Pace in Lake Como and requested it be served on two plates so they could share.

They later shared a photo of the receipt showing the charge for serving two halves separately.

Writing in Italian, they said the charge was ‘unbelievable but true’, adding: ‘This has never happened to me in any of the places I have visited in the world.’

Lake Como is known as one of the most exclusive destinations in the world, with actor George Clooney owning a house by the water.

Speaking to Italian media, the bar owner, who has not been named, hit back saying ‘additional requests have a cost’.

‘If a customer asks me to make two portions of toast, I have to use two saucers, two napkins and go to the table using two hands,’ they said.

‘It is true that the customer is always right, but it is equally true that additional requests have a cost.’

The customer, also unnamed, was reportedly at the bar in Gera Lario, a small town located on the northern shore of Lake Como, with his partner.

According to the receipt, the pair ordered a fizzy drink, the sandwich to share, a water and a coffee, for a total cost of €15.70 (£13.52).
