The tech covered it with her bare hand and then put "antiseptic" on it actually touching the applicator to the wound. Ugh. How worried should I be? Tool that cut me had been in sealed pouch so I assume autoclaved. To make make matters worse, she nicked herself with one of the tools while doing my manicure. She did NOT use that tool again but I'm feeling very icky at the moment and mad at myself for not walking out.
