Anywhere I've worked no one, pharmacist, techs, clerks, even the people that stock the shelves in the store, was allowed to ring up their own stuff. If you wanted to buy a drink during your shift someone else had to ring it up. I don't think this is unreasonable either.
Personally, whenever I've had any med filled while I was working I never handled it. I asked the pharmacist or another tech to refill, count, and ring me up when it's done. I didn't want any involvement in filling my own medications.
