I did place an equal amount of responsibility on the pro who used poor judgement in this case.
But in my comment to you and Nord, I used the word "condone", not "participate". As you "would have enjoyed watching", rather than doing something positive about it, I consider your attitude to be condoning of the activity.
As to the comments you and PR expound re: varied tiers of pricing equalling varied service. Have you ever flown on a commercial flight? Why do the people who paid more get to sit up front, get more leg room, have edible food, wine with corks, free cocktails, and possibly, the prettier flight attendants? They get on the aircraft before you, they get off before you, and their bags are already waiting for them?
They are paying for the service they want! Certainly, to some it's a status symbol. Do you want that service? Ante up! I don't hear you bitching at any airline for having First Class! Isn't flying just about getting from point A to point B?
Do you want the best seats at the concert, with box cocktail service? Pay the price, but you won't get it for the price of sitting on the grass! Isn't the idea of the concert just about listening to music?
I could give you dozens of examples of this tiered service model. But since you (or others) feel it's directly affecting your enjoyment of a sport/event, you take selected offense at it. So to say "that's not what skiing is supposed to be about", is to say the ski resorts don't have the same rights as other businesses, possibly even your own.
Don't get me wrong- I'm not going to defend the same ski areas which have generally ripped off the public for decades in their greed, but don't blame the people who take advantage of these opportunities, because they can afford to! In fact, many students save like mad, not just for their vacation, but the extra necessary to take a lesson or two, so that they can enhance the enjoyment of their vacation.
But allow me to make a comment about liftline cutting by ski school students-
At many/most areas, it is a privilege, not a right! Even the Vail clients who have paid over $500 per day for a pvt lesson can not just cut right in. The instr MUST ask if they MAY alternate in with the line. They MAY NOT just barge in. And if they do, tell them NO! It is your right to decline letting them in. And the professional instr's will let you by, and ask the folks behind you. The instr's (for the most part) do realize the time you have spent in line, and will be considerate. Very rarely will an instr put students onto consecutive chairs. Usually, they will allow several groups(in Vail, the policy is 3-4 groups) go by between each group of students, with the instr going up last.
