In April of this year, Barb and I attended a performance by Blue Man Group in Columbia, MO. Prior to the show, you could register to win a "trip back stage" by providing your email address. Barb did.
Five minutes after checking into Treasure Island Hotel and Casino in Las Vegas on Friday, she received an email from… Blue Man Group, inviting her to come see their show while she’s in town.
I’m guessing they have some sort of arrangement with with all the MGM-owned hotels that allows them to match the email database against guest as they check in. As far as I know, they have not abused Barb’s email address since collecting it. They were waiting to use it in this –or some other equally clever– way.
