I work in customer service.... pet peeves? Let me count the ways!
I work tech support for an online school. I deal with the following on a regular basis.
I HATE when people say "You people."
I hate when people call me for help, then refuse to do what I ask or tell ME what I need to do.
I hate when faculty says, "You guys need to get your website under control!" (You're a teacher, asshole! WE work for the same company! Eat a dick!)
I hate when Doctors demand to be addressed as "Dr."
I hate when the concept of "tech support" equates to "master of the dark arts" and people feel I should help them remove malware from their PCs for free just because my job title falls under "tech support."
As for my grammar peeves... I respect people who do not wish to identify as her/him, but to ask me to refer to you as "they" is unforgivable! "They" is plural. I do not consider you're alter ego enough to make you more than one person. If you can't pick a side of the gender divide, thats fine, but come up with a grammatically correct way to identify yourself!
Wow, I'm super heated about this. 🙂
