I love reading shit reviews on Tripadvisor, some of them are priceless.
I remember looking at some reviews for the Wedgwood Museum before when I was going to send my mom there for some pottery experience thing, had some woman giving it a horrendous review for being poorly signposted around the City, another who'd grown up in Stoke but moved away gave it a terrible review because the old factory was being demolished on the day she visited, destroying important heritage and what not, love how these events completely separate to the attraction itself are powerful enough to downgrade the review.
I think one of the best complaints I've ever heard was whilst working at IKEA, pretty standard shit without something showing as in stock but low and behold there's no stock there, however this customer tried to lay it on pretty thick to get his way, 'I've come all the way from Bradley for this' he proclaimed, not quite sure what sort of reaction he was anticipating when declaring his comfortably sub 10 mile round trip but the one he received didn't seem to appease him.
