Well, this is a little different since this family member wasn't actually a patient, but she was "acting up" and I was quite embarrassed about it.
My grandfather was in ICU. It was the middle of the night and he was near-death so many family members were present (the visitor policy only allows for two visitors at a time, but his nurse was kind enough to let us all back). My step-mother decided she wanted some coffee, so she asked my grandfather's (very busy) nurse to make some. Now if she had maybe said something like: "I know you're busy and it's not your job to make coffee for visitors, but if you get a minute, I would LOVE to have some," that might be OK, but unfortunately that's not how it came out. It was more like: "Can we have some coffee?" You have to understand, she is one of those people who is always finding something wrong with everything, so she had already found a few things to complain about that night. When she "placed her order" for coffee, I just cringed, because I knew she had already been bugging the nurse all night, and I just put myself in that nurse's shoes and thought "poor thing."
Well, my stepmother waited 15 minutes for her coffee, and decided that the waitress...I mean nurse was taking too long so she decided to go to Dunkin' Donuts. So when the poor, sweet nurse came in with my stepmother's coffee, guess who got to tell her that we no longer wanted it. Me...because my stepmother was at Dunkin Donuts.
