I worked for a guy who ran an exclusive, foofy, insanely expensive health club. He took 100% of what should have been (back then, when Ads were King) his advertising budget, and instead put ALL of it into a monthly "member surprise" budget. Nobody ever knew what was going to happen. You'd be in an aerobics class with 100 people (it was a big place), and as you walked out, suddenly there were carts loaded up with bowls of frozen yogurt and a toppings bar. You're in the weight room when the employees start walking through handing out exclusive t-shirts, always with his logo, and always with a fun quote, that you knew would never appear on a t-shirt again. Members collected these things like rare beanie babies. The late-night exercise classes were the hardest to fill, but he would take the worst time slot and make it interesting... the 9 PM folks might walk out of class only to be handed a wine cooler or even a relaxation CD.
