Customer: “YOU GAVE ME A VIRUS!”
Tech Support: “I don’t think I’ve got a virus.”
Customer: “Go download [a brand of virus checker], and you’ll see.”
Sometime later I dutifully ran the checker.
Tech Support: “Ok, I ran it. No virus.”
Customer: “You MUST have a virus. You gave it to me. It was all over my system. You must not have run the checker properly.” (yell, rant, rave, repeat checks, etc)
Tech Support: “How did I give it to you?”
Customer: “On those floppies with the latest revision of the software you wrote.”
Tech Support: “The ones you just returned?”
Customer: “Yeah.”
Tech Support: “Just a sec…let me check those.” (pause) “Well, I found a virus on the disks. Ahem…seems you were about to pass a virus on to ME.”
Customer: “Ah…lemme get back to you.” (click)
