You might want to inspect your bill closely the next time you stay at a hotel. Thanks to the plunging economy and the decline in travel, hotels have come up with all sorts of ingenious new ways to make money, as you may have noticed. Take, for example, the pool or exercise room that you had no intention of visiting anyway. You may end up seeing a "facility free" or "resort fee" appear on your bill, even though you went to Denver on a business trip, not to swim laps, and you've never heard anyone even use the words "resort" and "Denver" in the same sentence. You're perfectly aware that drinking a miniature-sized can of soda from the mini-bar will end up costing you $10. These days, though, you may also get slapped with a $1 "mini-bar restocking fee," which accounts for the 3.2 seconds or so it took someone to replace that $10 can of soda you just consumed.More
