A Houston bartender posted a TikTok sharing the three main red flags among customers. “Three bar order red flags,” she said at the top of the video. Red Flag #1: Rumple MinzeThe first red flag, which she calls the worst one, was a harsh criticism of Rumple Minze. Red Flag #2: Extra Shaken MartiniThe next red flag she lists is ordering an extra shaken martini. Red Flag #3: Crown Royal Old-FashionedThe last red flag the bartender listed is ordering a Crown Royal old-fashioned.
