Over the years I’ve enjoyed numerous buffets in pubs at various events. But a perennial problem is that plates of mixed sandwiches are put out without any indication of what the sandwiches are. Now, I don’t eat egg, and so am constantly worried I might pick up what I think is a cheese sandwich but turns out to be egg. But if you’re a vegetarian the problem is far worse. Especially in poor light it can be very hard to determine exactly what is on a sandwich, and you could even miss out on something appetising because you didn’t know what it was. So surely it would make sense to put out all the same type of sandwich on each plate, and if possible even to attach little signs saying what they are. The principle that “not everyone eats everything” could also usefully be adopted by those who put together pub menus.
