I've asked many stores such as A&P, Pathmart, and Shoprite.
They all say, "No"
I don't know where else to ask in order to shadow.
I live in New Jersey. So if anyone is from NJ, would anyone know a generally good place to shadow a pharmacist.
Try a hospital or independent pharmacy. Many chain pharmacies will not allow students under 18 behind the counter due to liability issues. Also, ask your high school guidance counselor if there's a program available that offers professional job shadowing. Many HS's offer this and have contacts they regularly use.
