Wowza, may I ask what you took and how much of it? The -only- thing I can think of is that you took a very non-dangerous amount, or he was having a very bad day. Regardless, that is no reason to say those things.
Even if someone takes 2 tylenol and calls in a panic, the person should be treated with respect.
Honestly when I first read your post, the absurdity of what he said gave me a chuckle because it just seems so outlandish that someone would say such things. Humans always continue to surprise me.
