It's a good thing I have a sense of humour.
I picked up a prescription this morning. The pharmacist said I had 2 ready. No problem since I also pick up for PA and the PR. I pay the bill and walk off. I notice that one is for someone I never heard of and they are for the same drug, mine. I go back and the pharmacist refunds me the $3.75. I walk off and notice that she should have refunded me the $12.91 prescription. Back to the counter and finally get it all sorted out.
