At my old hotel, a co-worker of mine threw me a little surprise birthday party, and used someone's top tier.

She was like "I thought it was extra" because it was still in the cooler that Monday, the MOB hadn't picked it up yet. Whoops.
I have been stolen from in every way possible. Mostly by employees. My favorite was the "Great Clinique Heist". Clinique was having a meeting at my hotel, and we stored a ton of boxes of makeup in a closet for them. Sometime, in the middle of the night, someone went through all the boxes, picked out the products that they wanted, makeup brushes, etc. I'm talkin THOUSANDS of dollars of makeup stolen.
One of my female PREGNANT employees was sneaking into my office and stealing my credit cards and using them. At the Columbus Day sale she bought a mountain of stuff at macy's, then later spent $900 on Calvin Klein Jeans and $1300 in the toddler boys dept. at Lord and Taylor. Her roomate, another employee of mine, turned her in, and she was arrested, sent back to Columbia.
