Callme, I hate that too. One time I got a migraine at work, outta the blue, so I asked my then manager if I could go home. The little ignorant 17 year old said, "When I see you getting a headache, I'll let you go home." I widened my eyes. "You mean you can see in to my head and tell when I'm getting a MIGRAINE, not a headache!?" (Very sarcastically of course.) He glared at me and said he should write me up for insubordination. (I think he tried to use a big word to impress me, LOL). I told him to Google "difference between migraines and headaches," then that I was leaving and I hoped he had a "lovely rest of his shift", (******* didn't get the sarcasm the second time!)
