The diabetic who "nearly lost her foot" should never have even gone to a manicurist in the first place. If she cannot feel her feet, then no way -- she needs a podiatrist. FACT and as a diabetic, she knew that too, especially if she's had it long enough to acquire that level of neuropathy.  I know quite a few nail salon owners who will not touch a diabetic - IF the diabetic tells them! If the equipment is sanitized, no problem anyway. BUT as a diabetic, she has no idea where she got that staph infection!  It could've been from kicking her toe into the table at the diner. It could have come from being in the hospital or doctor's office, where MRSA is highest! Again, your "evidence" is nothing but hearsay.
