With all due respect, I think this statement oversimplifies what can be a complicated situation. Deliberately showing up late for no reason is rude and inconsiderate, but there many varied and valid reasons why someone might be late, including illness, a delayed flight, a monorail breakdown, a family emergency, attending to a medical need, etc. These unforeseen circumstances have nothing to do with people being rude or inconsiderate. While I agree that if the cast members say no, you have to write it off and get a different fastpass, for some families Disney is a once in a lifetime thing and missing out on any one experience might be a tougher pill to swallow for some than others. For example, consider the 5-year-old who misses her chance to ride Peter Pan and see Tinkerbell, her favorite character, because her brother had a seizure and there are no longer any FP available for that ride. I don't think it's rude or inconsiderate to ask for an exception so long as one is willing to accept if the answer is no. While some people showing up late may need to work on time management, it is in my opinion not fair to make the judgment that it is true for everyone. Remember, everyone is fighting a battle you know nothing about.
