Being surrounded by sysadmins, it's either a sysadmin with a lot of customer experience, or there's a manager that has a lot of people experience. Many of the sysadmins I work with send either very terse or very verbose notes full of jargon, and we need to go un-jargon/uplevel them before they get to the customer.
I think it's partly a by-product of our annoyance that the end user had to seek our support in the first place. Kind of "we fixed it, this is what happened, it's not my job to explain the memory subsystem to you"
