Two very patronising staff in Pret tried to tell me that the broth they gave me when I ordered miso was miso and/or the same as miso. I pointed out miso is fermented soy beans and broth is boiled bones and they said 'yes! It's the same'.
WTF?!
I persisted but it was like trying to explain heaven to bears.
I didn't bother asking for a refund. They'd have asked for more money and told me that was the same as a refund.
