There is a new temp girl at my work and she says "brought" when it should be "bought". i.e. today she said "my boyfriend brought me some flowers on the weekend". Or if you ask if she wants something from downstairs she'll say "oh no thanks, i already brought a sandwich from the cafe". She also will say "i seen xxx on level 2" (instead of I saw).
I really, really don't want to be mean or anything and i'm not being high and mighty at all but I have heard people snickering a couple of times, and i wonder if i should say something to her. On the other hand i feel like i can't because she's in her early 30's so i assume she'd take offence. It makes her seem unprofessional, and i think it will let her down because she is quite bright.
