I'm going to remember that for my next mental insult!
But tears, man. I'm one of those people whose every emotion comes out as tears -- nervousness, anger, frustration, shock, fear, happiness, sympathy -- just everything. I really dislike it about myself, especially when I'm having a firm conversation with some company rep, trying to make a point about bad service. The worst, of course, is crying at work. Gah!
I agree it's not intentional. Patients certainly don't expect the person taking a blood sample to be our best friend, but there are times when, say, a needle-phobic patient needs a bit of extra patience and understanding. I did once write a complaint letter about an MRI tech; who knows what came of it but I felt better getting if off my chest. On the other side, I've written three letters to specifically thank health care workers, so positive interactions have been much more frequent overall.
