As long as there were no cameras in the bathrooms themselves, you have nothing to worry about. Collection facilities practicing in the US are prohibited from placing cameras inside the bathrooms. That constitutes "voyuerism" and is against the law. If you notice any cameras in the bathrooms, you need to report that facility to your States Attorneys Office pronto! In addition to criminal charges being filed against the facility, the aggrieved donor is also entitled to civil damages as well.
