Re the Giffen Good -
It's a theoretical possibility, but one which is almost never found empirically. The reason for an increased demand with an increased price, however, is not the perception of quality - and is not a theory applied to luxury goods. A price change can be decomposed into two effects - one based on relative prices, and one based on changes in one's income. The "pure" price effects are always negative - when a price increasew, demand decreases. However, when prices increase, one's purchasing ability decreases. Most goods have positive income elasticities - as one's income increases, one purchases more of that good. Luxuries are goods with income elasticities greater than 1 - the increase in purchase of luxury goods, in percentage terms, is even greater than the increase in income. There are some goods with negative income elasticities - as income increases, their percentage share of consumption decreases. These are goods like food. If someone with a $20,000 income consumes $5,000 worth of food (because it is a necessity), someone with a $200,000 income does not consume $50,000 worth of food. The theory of the Giffen Good is that a commodity could have a negative income effect which was large enough to offset the price effect. In this case, a good's price would increase, which would cause a decrease in a consumer's wealth, which would case an overall increase in the good's consumption. However, when economists get down to measuring actual price and income elasticities for goods, they've never found a "Giffen Good" in practice.
Re discounting and daily-fee golf -
The good rule of thumb that I've heard for estimating greens fee revenues is 2/3 of the top greens fee times the number of rounds - that is if you plan to charge $150 per round, and plan to do 10,000 rounds of golf, you'll probably realize $1,000,000 in greens fee revenue. The difference is due to the number of rounds which will have to be discounted for group, comped and non-peak play. Maybe a top-tier golf course can get away with less discounting, but even then it's questionable whether they're maximizing their revenue, and it's certainly not the general practice at most daily-fee courses.
