Aye! Well said lass! 
Lol! Myself, I say 'tea' (for the evening meal) and 'lounge' sometimes - not because of any particular attachment to either word, but rather to be better understood & to assimilate. No one I know here says 'supper' for the evening meal (unless it's a snack just before bedtime), and 'sitting room' ?!!! No, not that either. 'Sitting room' sounds far too posh (and slightly old fashioned), and therefore, annoying.

I grew up saying 'dinner' for the evening meal (except for Sunday dinner which was at lunchtime) - but here that means lunch, and would be a source of confusion. And 'living room' and for the sofa - we called it a 'divan' in my childhood home. I think one of my neighbors here calls the sofa, the 'settee', but I've not heard settee used that much - just IME.
Back to the 'fixing to' thing, sometimes that also comes out as 'fittin' to'.
