I've found this thread really interesting from a linguistic pov. I've always had a visceral reaction to certain language and "picky bits" is right at the top of my list. It turns my stomach and I have to physically stop myself from grimacing when I hear it. I've always noticed that it crops up repeatedly on threads about words you despise (and many of them are food related eg plate up, meal, yum, treat) but this level of reaction has made me think. Why do these words evoke this reaction? I know for me, picky bits seems to evoke scabs and skin conditions or referring to food, the notion of "picking" seems to conjure carrion picking meat from a bone. It's so deeply unpleasant and it's not just me evidently. It's not class either, I know people from all spheres who say it.
I think there's something else at play with Markies and it's not regional. I remember a thread many years ago with a new Mum in the grips of PND who could not cope with the sing songy motherese her husband was using. She said she could tolerate it normally but while exhausted and struggling, it was making her want to scream. I've seen this reaction quite a few times over the year. It's nothing to do with dialect really but the singy songy twee shortening of words. Here you wouldn't hear Markies (it's Marks's) but do hear Sainsbo's, Dotty Ps, MaccyDs etc and that sort of language is what we do with toddlers. Doggies and horsies and milkies and biccies and so on. In adult only company, it feels infantilising to some people I think. As an aside, I was out to dinner once with DH's colleagues and partners and one woman referred to it as "din dins" before cutting up her boyfriend's meat. I was aghast but weirdly, the language was the worst bit.
I was one of the people who saw the thread title and 100% assumed it was a goady thread about despised language and was surprised to see the op was being earnest.
I'm an adult of course so manage not to lambast those who use language that I find unpleasant but I find it fascinating nonetheless that there is such a level of reaction to the same words and use of language.
Anyway op, just order in some frivolous food periodically with your normal deliveries. Goodness only knows, life is miserable enough so cheering yourself up is a good thing.
BTW, do M&S still do those biscuits that are a sort of flat shortbread with half a covering of chocolate. I used to babysit for a family who left them out and having never shopped there, I was always a bit in love with them.
