Tut tut OP
On these threads we always get told that
The royals have to do more preparation for these events than we will ever know
Don't they do better than any potential president of a republic (with all his / her degrees, relevant experience backing of the electorate) could ever do? Mmh? Think about Boris!
Isn't it great that they are raising awareness of needy causes? It seems that some people didn't know about foodbanks but Wills and Kate have swept in to put an end to that - the plight of the poor has now been highlighted, the tireless volunteers have been rewarded with a few minutes of "did you come far" and other insightful questions that show how engaged and enthusiastic the royals are and that "they know their stuff".
This is the best possible way to spend public money. It probably didn't cost anything anyway. And even if it did, you aren't stupid enough to think that the equivalent amount would help the NHS / underpaid public sector workers / poor infrastructure? Don't be daft. We live in the best possible world and with any other party in government things would be much much worse.
Poor Catherine is a mother of three and she is busier than you will ever be. And didn't she look lovely? You are just bitter and jealous of her swishy hair.
Well it's more than Harry and Meghan are doing, isn't it? Wait, are you saying that Meghan actually used to volunteer at soup kitchens? You must be team Sussex / a paid bot / naive / lack critical skills.
Etc etc.
By the way that was sarcasm. I totally agree with you OP. That there food banks is a symptom of a breaking, failing society. For someone as privileged as the heir to the throne plus one to go there for a few minutes to make themselves look good is grotesque and insulting.
