possible mini job with lots of interaction with strangers

possible mini job with lots of interaction with strangers earlier at dinner with my family, the girlfriend of my brother suggested a mini job as a strawberry seller in these small cabins. I was looking for a small job besides school anyways but didn't find any near that accept underaged (I'm 17) and if I found something, the distance would've been too long. so I was googling a bit and there are more in my area that excepted. I'm really thinking of applying but the human interaction with strangers make me nervous because my stutter is quite intense - and I have blocks (but these days I have more prolongations than blocks tbh!) I fear of blocking on numbers with vowels at the beginning (I speak German so 1, 8, 11, 18, 80, ... - not many, but some) but I also think that something like this can help me, like getting more comfortable after some time. what are your thoughts? also, what are your best advice for stuttering? maybe "stuttering techniques" or just ways to become more relaxed
