I checked into Borgata mid-week last week. I was comped a classic room, but I asked if any upgrades were available. The gentleman checking me in said "I'll take care of you, you take care of me, alright?" or something to that effect. He gave me a Water Club room, along with a 1pm checkout. When it was all said and done, I gave him $20 tip. His reaction to the tip seemed like he was't too happy with it, although I only got a brief look as I walked away.
No specific questions. Just wanted to share this story and see if anyone here had thoughts or similar experiences.
