"Hello, sysadmin Jenny speaking"
"I want to talk to the sysadmin, not to support!"
"Yes, I'm the sysadmin for the mail servers."
"No, I mean, the person who actually works with them!"
"Yes, that's me."
"No, I mean the technical person, not support or customer service!"
"Yes, that's me."
"NO! I need to talk to the TECH PEOPLE!"
After a while I gave up, muted my phone and called around the office "There's a guy here who doesn't believe I'm actually working with the mail system. Can one of you guys (all of whom were men) please talk to him?"
