I left this past Saturday to go to the Sierra national forest to go hiking. Upon my late arrival back that evening (10pm) I find a note saying 100% non smoking. Your company will be notified. The next morning I ask the guy at the front desk (Aeric) who calls the gm. The gm says she personally inspected the room and smelled smoke. I let them know I do not smoke. I dip smokeless tobacco. At this point they still are not backing down from charging me the 250 charge. I leave the window open when I leave and I know the smoking area for the hotel is right below it so lesson learned on leaving the window open.
