Here's a few of my hates, that I can explain through stupidity of people learning - usually from the telly - the USA or Aussie vernacular
TV - instead of television or even telly (and no not the trans gender sort of TV)[
!]
Can I get? instead of Please may I have?[
!]
Uni - instead of University (bl**dy Neighbours)[
!]
Have a nice day ... mind yer own business what I do with my day:D
That's enough for now or I'll blow a blood vessel or two:D:D
