A few years ago, back in college, I worked part time at an Embassy Suites. Before that I had worked at a Choice Hotel where all you did was haggle. Naturally, at Embassy I did the same for same day arrivals. Managers didn't like it much though. Every time you lowered the rate on the system a pop-up box would emerge where you had to type in why the discount was offered. I suppose "He was a nice guy" or "Took what I could get" wasn't a valid reason for them.
