Off topic a bit, but when I worked as a clinical chemist, I was running the diabetic clinic one afternoon. The next patient blew his nose into his hand and then offered me the same hand to do the thumb prick on. GROSS I could not conceal my disgust and gave him several antiseptic wipes.
Actually I could start a whole thread on the gross things in hospital life.!!!
The poll, all annoy me, but seat recliners are the limit. I normally slide down in my seat and shove my knees into their back.If that does not work I slam the table up and down.Most normally get the drift.
