I work like a dog to make my rental beautiful and clean and welcoming, and I NEVER give discounts. I did only once -- to a "starving student -- from Texas who claimed he was starting Princeton when he left my rental in Yosemite. He wanted me to take $50 off, writing "for example, you could waive the cleaning deposit" and offered a figure that he could afford. It turned out to be $100 MORE than I was asking, so I said sure, I'll take that. He turned out to be a complete punk, though his girlfriend was very sweet. The hot tub rules said DO NOT TOUCH THE CONTROLS, but he did it anyway and turned it down 10 degrees and left it that way for me to find in the morning. It costs money to heat 300 gallons 10 degrees and I was absolutely furious. But he was just my third guest party and I needed good feedback. When he left he stole at least $150 of food that I had stocked for guests, plus two $150 LL Bean new cotton terry bathrobes for the spa, and left the place a mess. I called him on his cell phone and told him to bring everything back. He sneered at me: "What are you going to do if I don't?" I told him I would call the CHP because there was only one way in and one way out for the next 75 miles, and he would miss his plane to "Princeton." He turned around and drove back and the coward sat in the car while his mortified girlfriend returned the items and apologized. She said "He told me it was complimentary."
I told her to be sure to tell him that the price he suggested and that I accepted was $100 more than I charged for the room. She laughed and said he was a jerk and it served him right. He left me a so-so review because he didn't want me to write that he stole from me. I damned him with faint praise. A couple of days later I called the Princeton admissions office and -- big surprise -- they had no record of him whatsoever. I will NEVER give anyone a discount again.
I raised my prices and got a much better class of guest and no one ever asked for a discount again. but if they do, I'm going to decline it instantly and click the "I do not feel comfortable with this person" button as the reason, because that's the truth.
