Since when was “dude” an appropriate honourific to use in business communication? Okay, the “business communication” I’m referring to here is spam, so perhaps I’m being too picky. But before someone insults my genitals, offers me a mortgage in the U.S., or tells me how I can get rich by having a university degree*, I want him to call me “Sir”.
*But I have a university degree. Why am I not rich? The last time I got one of those “a degree will get you $30-40,000 extra a year” messages, I forwarded it to Magda in payroll. She laughed.
