Sometimes first dates or nights out just don't go to plan and you might find yourself in an uncomfortable or potentially scary situation.
In bars, clubs and licensed businesses across London, the Met Police have a safety campaign known as Ask for Angela, which allows you to let staff know you're in need of assistance without causing a scene.
But it seems there might also be another way to signal that you need help - especially if you're going travelling in places like the US.
A bartender from Los Angeles named Benji Spears went viral online after explaining the simple code word you can use that will alert bartenders to your trouble - and your date will likely be none the wiser.

In a TikTok video, Benji reenacts a situation in which he's working behind a bar and spots a woman on a date who he thinks looks uncomfortable.
When her date nips to the bathroom, Benji goes over to check all is ok, offering the woman some help and explaining to her what an angel shot is - and how there are three different types/meanings.
He says: "Angel shots are becoming more common and more known throughout all bars and it's being brought to bartender's attention.
"Ok so an angel shot is key, it can save you or your best friend's life and it's something we should all know about.
"So there are three ways you can order the angel shot, you can do the angel shot with lime. Ok so angel shot with lime when you order it, it means you need the police so the bartender will notify a manager and we'll get the police involved for you.
"Second you can order an angel shot neat, that means you need someone to walk you to your car, a bartender or security, someone needs to walk you to your car because you don't feel safe."
And the final option was an angel shot on the rocks, which means you need the bartender to call you an Uber or a taxi to get you home safe.
Benji adds: "I think this is a great learning lesson. Everyone should know about the angel shot.
"It's just a great way to make sure that we all feel safe."
The video has garnered lots of attention, with one person saying: "An angel shot with lime actually did save my life. Thank you for posting this."
Another replied: "You are an angel for posting this."
