My girlfriend and I went to a concert at the symphony orchestra. The event was downtown and the people I was with and I did not want to drive back lake home after the show ended. My girlfriend made reservations for the 2 of us to stay at a nice hotel a few blocks away from the place. Both of us were close enough to walk or take the subway. Both of us inspected into our hotel room before the show started. Both of us did not have a lot of bags or items to take up to the room. When my girlfriend and I got settled into the hotel room, the people I was with and I adjusted the Heating, Ventilation, and A/C machine and turned on the a/c. It was hot and the air inside of the hotel room seemed stagnant. I hoped turning on the a/c would help with indoor air conditions. The a/c turned right on and chilly air started coming out of the vents. After a few minutes, the room was starting to get much cooler. Unluckyly, there was a weird and unusual odor coming from the AC unit. I couldn’t tell where the smell was coming from, however the smell only occurred when the a/c was running. My girlfriend and I mentioned the problem with the AC to the front desk clerk as the people I was with and I were getting ready to leave. The guy provided to send someone to the room while the people I was with and I were gone and my girlfriend thought that was a fantastic idea. When the people I was with and I finally got back from the symphony, the people I was with and I finally got our chance to check on the a/c. When the people I was with and I opened the door to our room, the people I was with and I were cheerful to get hit in the face with a blast of chilly air.
