Biggest mistake made on the job?

[Rio_Kohitsuji]

When I was a clerk at a local pharmacy I did I BIG no-no. It was a typical busy-beginning-of-the-month-5:00-rush-hour, well, I was freaking swamped with orders and calls. Well, in all the confusion I had given a #2 customer 2 full bottles of OXYCOTIN that was supposed to be for #1 customer!!! I realized the mistake due to the signitures on the sign sheet, the only difference between their names was the damn middle initial!!!! I had to practically sprint through the dag on store looking for her!! Man, I got ripped for that one!
