I had a call a with a person who accidently brushed her teeth with cortisone cream instead of toothpaste. This person called poison control and was told that it will not hurt her. She still felt the need to call the ambulance for confirmation. I simply explained to her that poison control was correct. I wanted so bad to say to her, your fine dingbat and your teeth won't itch either, but I didn't.
Had another call on the same night....no less....transported the person to the hospital and while trying to obtain information and signatures from the husband he asked me, "do I sign my name?" I stated that would be fine and you can write husband after your name. He stated to me, "I am not her husband, I am married to her." The sad part is he was totally serious.
These are two examples when I would use my easy button.
