i agree with what people have said (at the point I am writing) that you should go for it. it looks like a great opportunity for a lot of small interactions. have a good interaction? great, keep it going! didn't have a good interaction? soon you'll have another chance! as for stuttering techniques: i like a slow rate, and you can try easing into and/or elongate the vowels you are having trouble on. try and see what works for you. and good luck!
