My cousin is a M&S manager.
She lives near my elderly parents & frequently tops up their freezer with staff discounted/free because sell by date food. Which is nice of her & greatly appreciated.
Aged ps are comfortably off but do love a bargain; cousin is especially close to my mum since her own mother, my aunt, died; I live far away so am not able to perform regular freezer filling - everyone is happy!
But the food really isn't all that. When you stop seeing it through a lens of unctuous advertising & instead it's 'oh we've got three of those lasagnes in the freezer, meh, I'll do that for tea' - it's actually a very very average supermarket lasagne.
Aged ps now look forward to my visits in part as I cook & freeze far nicer meals for them, which makes a change from M&S meh when they can't be bothered to cook & just want something out of the freezer.
Also, there's the wankers in the women's changing room thing.
My mother won't tell my (lovely) cousin to stop shoving a few short dated ready meals her way - they are definitely useful if boring, plus she loves my cousin & doesn't want to upset her.
But she's certainly not planning on shopping there again, so long as her granddaughters, my dds, can't have a women only changing room to try on a bra.
