They reneged on the "lifetime" promise to the Flying Colonels when it proved to be convenient for them to do so.

They redefined what "lifetime" means. It now means the "lifetime of a DL Manager's integrity."

"Lifetime" is now roughly equivalent to the duration of a "lifetime" warranty that you receive on a used car from a street corner car lot that was not there last week and will be gone before the end of next week.

I don't mean to imply that anyone with a purchased lifetime Crown Room membership (such as brought over from NW) is in jeopardy... I am only saying that there is one data point that indicates DL Management has a peculiar concept of "lifetime."
