I experienced this first hand. Rarely do I go to Wetherspoons for food. Had done so only once before. But I'd looked in the larder that evening and saw nothing I wanted, so I checked the Internet and eventually decided to walk (in the drizzle) to the nearest Wetherspoons and try their steak club. (And wallop the diet.)
Got there to see a note on the bar saying none of 3 types of steak were available. Typical ! The one time I go there for a steak and they have issues. I tried to order have a gammon instead, as that was a normal dish, not a club night one. Not got that either.
I end up having a beef & ale pie (oh Lor' the calories) which wasn't up to that much. Taste minimal, hard peas reminded me of school meals.
It was only today I discovered it wasn't that pub alone, it was 900 up & down the country ! What a screw up !
(Luckily I wasn't told I could eat pet food instead or I may not have been able to remain calm. That would have been maliciously pouring salt into an open wound. Sick sense of humour, some folk.)
