It's understandable that you feel anxious about ordering drinks in a loud bar, especially when alcohol can affect your speech. However, there are a few things you can do to make the experience easier and more comfortable for yourself. Firstly, you could try practicing ordering drinks in a loud environment with a friend or family member beforehand. This can help you feel more confident and prepared when you're in the actual situation. You could also try writing down the name of the drink you want on your phone or a piece of paper, so you can show it to the bartender if needed. In terms of drinks with simpler names, some options could be beer, wine, or basic mixed drinks like vodka soda, gin and tonic, or rum and coke. You could also try ordering a specific brand of alcohol that you're familiar with and know how to pronounce. Another option is to use an app or device to communicate with the bartender. For example, there are apps available that allow you to order drinks from your phone and have them delivered to your table. Remember that it's okay to take your time and communicate in a way that feels comfortable for you. Don't let your stutter hold you back from enjoying your trip and having fun with your friends.
