Glad you got youre Meds and Tampa did as much as possible to protect your script...thats good service.
I believe all the situations that had wrong meds were in "tamper proof" envolopes.
What I think is happening is they tear it open then put it in a new one so it doesn't looked tampered with.
I like that tamper proof tape idea mentioned earlier. I think it will help alittle if the tape is not easy for them to get.
