1. Grammatical pet peeve
As an English major I probably have many -- however, as someone who grew up with some interesting, colloquial language uses herself... well, see below.
My biggest pet peeve here? Probably poor spelling or the improper use of the apostrophe.
2. Household pet peeve
Hmmmm.... Leaving food on the counter after dinner instead of putting it away? Ooo.... actually, when my husband trims his beard and doesn't clean up (entirely) the "droppings."
3. Arts & Entertainment pet peeve (movie theaters, restaurants, concerts)
Crabby, snooty or inattentive servers, or on the other end of the spectrum, over-attentive, insecure servers. My DH and I have both waited tables in the past and have come to expect good service.
4. Liturgical pet peeve
Breaking the bread when saying the words "and he took bread and broke it" ... I was taught (drilled) that the words of institution are a remembrance, not a re-enactment. Not that how I learned or how I do it is "right" or that it really matters... :)
5. Wild card--pet peeve that doesn't fit any of the above categories
Driving pet peeve: People who don't use their blinker. My snotty response? "I think blinkers come standard on that model..."
Bonus: Because all have sinned and fallen short of the glory of God: What do YOU do that others might consider a pet peeve?
As I indicated above, there are a couple of things that I say that probably make others shudder. I grew up saying things like, "Do you want to come with?" I've learned now to say, "Do you want to come with ME" or "Do you want to come ALONG?" Also, it's a regional thing, I've discovered, to say, "I'm going to go put gas ON the car" as opposed to IN the car, which seems safer, clearly, but ... well, some things are hard to break!
