Just to make sure... you aren't asking inappropriate questions or at the wrong times are you?
You don't want to start interviewing pharmacists when you go to volunteer and ask them questions people often ask here like which schools don't require PCAT, what people GPA were and where they got accepted/interviewed, how well they scored on NAPLEX, if they have a chance to get into pharmacy or not. Those would annoy almost any pharmacist, especially if they have been a pharmacists for 20+ years, when the system was very different.
I volunteeer at hospital and I am sent to do so many things where I volunteer (never involves cleaning things, most labor work is delivery and taking out meds from boxes), I only ask questions about things happening (like events, meetings, etc), when they talk about some drug I ask them about it, and do a lot of listening when they discuss a patient (you don't want to compromise patient confidentiality). But while there is some labor work, if you do them quickly and well, they will often assign you to more pharm tech jobs (restocking meds for more than an hour gives me eye strain, so I'm glad I don't have to do it if I dont want to). Being a tech might be more interesting and helpful to you, but I figure doing only 4 hours a week helps me with dealing with the hours for my paid job, because two part time jobs would be really hard while taking 14+ units of upperdiv science classes and getting A's to raise GPA. And as a volunteer there is a bit more flexibility when it comes to extra work once the necessary tasks are complete.
