We’ve all been there, BAD DATES! But, if you’ve ever needed an “emergency” excuse to leave, then you’ll be excited by a helpful trend happening in bars across the globe.

At Iberian Restaurant in St. Petersburg, FL, this means there is a discreet sign in the women’s restroom that reads “Is your Tinder date not who they said they were on their profile? Do you feel unsafe or even just a tad bit weird?” If so, the sign advises, “order an angel shot.”

An angel shot is actually not alcohol at all. The Tampa Bay Times reports, it’s a code that will secretly tell the bartender you need help.

For your safety, this is how it works: order an angel shot neat and a bartender will escort you to your car. Ask for it with ice and the bartender will call a taxi or Uber for you. Order it with lime and the restaurant staff will call the police.
