One big hospital here has been packed many times this is the one I waited 23 hours in the er for a room once . I was told at that time they had a 20 hour wait that day ! I was sick last week and went back to this same one and waited 9 hours to get in the back not. But after 4 hour they did come out in the waiting room to give me meds so I was thankful for that . But it got me thinking what is the longest wait you have even seen .
