Absolutely seems legit and just a person doing their job, however - you’d have been within your rights if you wanted to be petty to say you haven’t been given your 24 hour+ notice (is it actually 48 now?) and so they can’t just turn up.
Don’t think it was particularly arsey - maybe a bit short/curt but I think that’s more because it’s a text and they’re probably working on all sorts at the same time.
