your transaction is declined - only joking

At what time did it become a good joke to tell the client that her card transaction was declined?

Then Hahah, I was only joking. Seriously, since when should my financial transaction be a source of amu*****t to a waitron.

Today 30 May 2021 at 13h30. 2 x fish and chips with a bottle of Two Oceans.

Not amused.
