I’m at JFK, I try to login to my pay as I go account & am told that I can’t pay as I go with my account. The circular logic of the error message was priceless.
Their solution? I should create a new acct & pay as I go. This will be awesome by my 5th or 10th use of this genius system.
Kudos to those application developers and all I can say to the database engineers who have to mop up that multiple account garbage is, enjoy and take it up with your devs.
