My gf works in inside technical sales for an industrial instruments rep/distributor, and therefore a large part of her job is passing information between customers and manufacturers while trying to keep both happy and process orders. On a good day, she probably is forced to send the same requests for information at least two or three times on average before finally getting an answer. People just refuse to read even extremely short emails asking for straightforward information like shipping addresses which simply must be provided to proceed with the order. I wouldn't last a month doing her job without losing my damn mind.
