04 October 2019, Italy, Rom: A man cashes in old plastic bottles in a vending machine for subway and bus tickets - a snake has already formed behind it. The passengers put the plastic bottles into a vending machine that loads money for tickets onto the phone via an app. So far only three metro stations have such vending machines - but there are always long queues in front of them.
