Greasing 101: lesson #1

anybody had any success with greasing the the desk clerk? here is today's lesson from Mr DC.
If your hotel room’s too rocked, if you want a suite for the price of a single…just tip MR desk clerk. the desk clerk says: “I have total control to upgrade you from a standard room that costs around $175 to a luxury suite that costs $400. When you check in, slip a $50 bill under your credit card, lean over the desk a little, and quietly say, ‘It’s an important night for me, and I’d really appreciate it if you could get me a great room if you have one.’ Be discreet so the other guests don’t hear, and say it immediately, before I start all the paperwork. If you give me anything under $50, I’ll just tell you how much our hotel charges for an upgrade. Come as close to check-in time as possible: The later it gets, the busier we get. When you’re slipping me my tip, you can also say, ‘The rate was really high when I called. Do you have anything lower?’ I can knock off more than 100 bucks.”
