I'm 100% okay with being told IABU.
I work in a fast paced area, very loud and very busy - its hard to hear people and as a result asking someone to repeat themselves is the usual. I often have to ask ''What?'' because I didn't catch something.
My manager has a habit of saying ''Pardon!'' every time I say ''What?'' as a way of correcting me - Every. Single. Time. Its like having my mother in work.
AIBU to think she shouldn't be doing this every time? I could understand if I wasn't saying please or thank you, but I do. Just for full disclosure we're from different counties (I'm from the north), she also tends to correct the way I say things because of my accent.
