Walgreens once gave me the wrong prescription, which I didn’t notice until after I already taken some. It was some weird drug for schizophrenics or something like that and it totally fucked me up to the point I had to take off work for the day. Instead of apologizing or trying to make the situation right the Walgreens pharmacist was a total asshole to me and tried to blame me for what happened, they acted like I had stolen someone else prescription instead of them fucking up and poisoning me.
