Agree with the others about what to do in future. Many places are now organized for their regular clients and keep each individual's tools in labelled boxes.
Otherwise, just bring your own and if the salon objects, then find another one. An easy precaution worth taking.
For this particular incident, I personally would let it go but it depends on you. It's about blood-to-blood contact; the chances are remote but possible.
Pedicures are super, aside from that. :)
Appreciate the recommendations but what I'm wondering is about the transmission of HCV since this did already happen.
I use to live on pedicures and nails. noticed aprox 10 yrs ago this nail shop I went to started giving each client their own tools. dedicaited to one coustomer only. a box with your name and a slot to put it in.
Next time bring your own pedicure/manicure sets with you...
