Last night we went to Red Spice Road for dinner. The waiter brought us over to one of the communal tables and handed us menus full of exciting options.

While Damjan, Jana and Rajko discussed which dishes to order, I was half listening to the group next to us. The man and two women were finishing up their dinner and called for the bill.

Five minutes later, I saw one of the women take out her iPhone and tap on the screen.

‘So…’ she said, ‘One hundred and eighty dollars… divide by three…’ The answer blinked on screen.

‘Okay, so it’s sixty dollars each,’ she announced.
