The group had spent €124 on pizza already.
A restaurant in Sicily is coming under fire after it charged a group of tourists €20 for slicing a birthday cake.
The group had already spent €124 on pizza at the restaurant in Palermo, and asked a waiter to slice the cake they'd brought along to celebrate.
The charge appeared as a service charge of €1 per slice of cake served.
Last week, it emerged a restaurant in the northern Italian resort of Lake Como had added a €2 charge for cutting a toasted sandwich in half for two customers to share.
