There's this thing about asking girls out at their job, but if you do it as non-creepy as possible it could work! I'm not saying all guys are terrible, terrible murderers/rapists/both, just to be clear but unfortunately thats just how the world thinks nowadays. I believe stuttering doesn't matter in relationships if you find the person who will love you for it regardless and be patient. It's pretty sad how much we hold ourselves back because of it. I had to learn to roll with it and not care about what others thought. If they don't like you for your stutter that says a lot about the person, not you. I hope this helps, you got this!
