A comedy club in Barcelona is experimenting with charging users per laugh, using facial-recognition technology to track how much they enjoyed the show.
The software is installed on tablets attached to the back of each seat at the Teatreneu club.
Each laugh is charged at 0.30 euros (23p) with a cap of 24 euros (£18). Takings are up so far.
The project was developed to combat falling audience numbers.
Partnering with advertising agency The Cyranos McCann, the experiment was a reaction to increased government taxes on theatre tickets, which in turn led to drastic drops in audience numbers.
The results of the experiment have so far proved positive with overall ticket prices up by 6 euros, according to the theatre.
The system is now being copied in other theatres around Spain.
The comedy club has also launched a mobile app as a method of payment, as well as its first pay-per-laugh season ticket.
The research said coffee in Scotland usually used more heavily-roasted beans and the serving sizes were larger.
The amount of caffeine per serving of an espresso in Scotland ranged from 72mg to 212mg.
This compared to a range of 73mg to 135mg per serving for Italian espressos and 97mg to 127mg in Spain.
A village in Spain is set to make history this week when it votes on whether to change the second half of its name.
The 60 residents of Castrillo Matajudios – which translates as ‘Castrillo Kill Jews’ – will vote on the name change after Mayor Lorenzo Rodriguez submitted the proposal recently.
The mayor says the town was christened with the name after a number of Jewish people were massacred in nearby Castrojeriz in 1035, prompting survivors to move to the Castrillo hill. A second massacre occurred there in 1109.
The Matajudios name is similar to a common expression used across northern Spain to describe a drink of lemonade and alcohol – ‘matar Judios’, meaning ‘kill Jews.’
Regardless of how the village votes, it will hold its annual ‘matar Judios’ event on Good Friday during which 40,000 gallons of lemonade is expected to be sold.
