There's a shopping centre near my office with a posh furniture store in it called Grange. I popped in to see if they had a particular sofa and the guy in the shop took a call, referring to it as Gronzj (iyswim). I nearly had to leave the shop laughing, it's worse than Cl'aam for Clapham or Saint Reatham for Streatham. AIBU to think this is ridiculously pretentious?
