Just had one.
After the usual flirting he asked me to put my computer on.
"How old is it"
Oh, it is ten years old. Usually I switch it on and go away.
"How's it going..."
Oh, it usually takes 15 mins to start up.
Spluttering. "Really, why are you not using our services? You should be using our services. 15 minutes is not normal"
Oh, I do use your services. When it switches on it says Microsoft, so I'm definitely using your services. 15 minutes is normal, that's how long it takes!
A bit more outrage from him, followed by
"Right, I'll call you back in 10 minutes, is that OK"
Only made it to 4:45 call length, not a record.
