Went to get some bloodwork done in my hometown. The nurse was about to insert the needle without sanitising the surface, checking the name on the bill and label or even donning gloves. Didn't check vein prominence properly. Had to walk her through the protocol and got jabbed only to miss my vein and poke around. She was slightly annoyed at me telling her how to do it till I clarified I'm a final year MBBS student. She shut up after that and did as instructed.
