My son just graduated from college and my SIL flew down to Phoenix to see him using a cut-rate airline that only flies on Tuesdays and Fridays. My son's ceremony was on Friday, so SIL missed it and let everyone know she was upset about missing it. Ms. Chip took the opportunity to point out that SIL would be missing the graduation specifically because of the airline she chose and, given that, the flight wasn't such a bargain after all. SIL hemmed a bit, but wouldn't agree she didn't buy what she wanted versus what was cheapest.
But I had a side conversation with her. She said the flight was cheap enough that she could use that airline to fly down and see us more often. We live about 200 miles from Phoenix, so it's a 3 to 3 1/2 hour one-way drive there. I pointed that out; SIL said she'd pay for gas. I said, "Still ain't happening," so SIL went for an overrule by Ms. Chip. Ms. Chip's response? "You can rent a car or fly to Tucson."
