Probably not the longest, but the most ridiculous. We have a big free African music festival in our city and there are loads of different food stalls with great food. There was a Kenyan one that my best friend really wanted to go to as she lived in Kenya when she was a kid, and the queue was big which usually means good food. However once we were in the queue we realised the queue was moving really slowly… No matter, it must be worth it when we get there surely… After 45 mins I really wanted to go somewhere else but the sunk cost fallacy and the thought of getting in another queue made me stay… After over an hour we finally get to the front and realise that the reason it’s so slow is because they have the most illogical ordering system that doesn’t make sense, and even the staff seem totally confused. An hour and a half later we finally get our food and it’s ok. Just ok. In a big field full of amazing food we managed to pick the most mediocre one, and stupidly queued along with loads of other stupid queueing people for no good reason except being in a queue.
