So, you showed your wallet EXP card, you showed your BP, and fine you switched seats with your wife, I have done that plenty of times, no issue.
The FA (sorry to other FA's that are well educated and very nice) needs to be reported. They are not doing their job.
I would not be happy, for a benefit that EXP are entitled too, not being exercised.
What is wrong with some of the FA these days? (I mean do they get a commission for the amount of snacks left in a basket after a trip?)
