Your children asking you when you will be going food shopping.
Yes, you can't blame little ones for not understanding; but for so many people, the assumption is that you haven't been shopping because you haven't had time or just not been bothered.
So many retailers' advertising campaigns work on the basis that, if they give you a tempting enough offer, you will succumb and buy from them. They either don't have a clue or just consider the poor as 'wastage' in their attempts to mass-market to their potential customer base.
Asda send out an email every Friday with the subject line saying something like "Stop scrolling - your offers are here!" I can only think that they assume everybody has spare money every week that they're desperate to spend on any old thing and are furiously trying to find a way to do so, but are too stupid to know how to spend money unless somebody actively tells them what they should buy.
It reminds me of that old documentary from many years ago, which showed Michael Jackson in the big, gold-dripping, rich man's souvenir emporium. The shop owner would point to another gaudy monstrosity, say "What about this?", Michael would give his assistant the nod to take it and you could actually see the shop owner rubbing his hands together.
Even all of the 'aren't we caring' emails asking if you want to opt out of emails for Mothers' or Fathers' Day are nasty and cynical. They couldn't care less about upsetting you - if they did, they wouldn't target you in the first place with such an obviously-triggering email. It's just their way of preventing people who find Mothers' Day upsetting from reacting by unsubscribing from ALL of their marketing.
Having said that, even if MD/FD are not upsetting for you per se for the understandable reasons, it's much easier to ignore other marketing that's targeted at you treating yourself when you have no money than messages saying "You know your Dad deserves a treat - show him that you really love him" by spending money that you simply do not have.
