This is Rich:

He’s in med school with me. We’re taking a class together right now, and today we were out in Belleville, IL (about 30 min from St. Louis) to learn all about Basic Life Support and Advanced Cardiac Life Support. We had an hour off for lunch and we were going to go to this little Mexican place Rich knew of, but they were closed due to a "Boil Order". What is that you may ask (I certainly did). Well, it means that the water pressure in Belleville was not high enough to ensure that contaminants would not leak back into the fresh water – thus all tap water becomes potentially contaminated and people are advised to boil it before using it. This also makes restaurants close down, since they can’t very well clean anything in dirty water. So everyone ended up going to Jack-in-the-Box instead.
