For the third time in a week, I experienced a newly popular faux-polite farewell, finally decided on the appropriate rejoinder, and executed it.
The offending statement is “You have a wonderful day!” and its many variations, uttered by someone who has behaved jerkishly, has been told so, and who doesn’t have the guts or integrity to apologize or acknowledge that he or she might have been wrong. It’s a sarcastic comment that means the exact opposite of what its literal words convey, deliberately contrived so that the speaker can feign innocence if he or she gets a harsh response, and can smirk inwardly for pinching off an adversarial encounter with a coded “Up yours!”
I don’t know when this trick became a fad, but it has. For some reason, everyone who has used it on me has been female. It is a passive-aggressive device. I first became aware of the “You have a wonderful day!” ploy when the staff at a doctor’s office informed me as I went in for scheduled treatment that I would have to pay many thousands of dollars on the spot though they never notified me of this in advance. After pointing out that I found their conduct unacceptable and unprofessional, that their explanation was dishonest, and that I would no longer be using their employer’s services, the snottiest of the desk staff fake-smiled and chirped, “You have a wonderful day!”
