I love threads like these. I find them really comforting. It actually reassures me to know that no matter how careful anyone is to try and avoid being annoying, someone, at some point, will find them despicable and beneath contempt.
I used to work in restaurants and I often used to say "there you go" without even thinking about it - largely because I think just putting a plate down in front of someone and walking away might be construed as a bit odd - and I am honestly delighted that it may have made some of my customers angry.
