Caffè Nero, like most British food companies, excel in graphic design and suck in food.
I only noticed yesterday how they advertise their “bread” as being so delicious not to “need” those usual flour enhancers, usually found in the common English rubber-bread. However it seems that needs are not the only behavioural motors, and their cold plastic-wrapped sandwiches do have emulsifiers and flour treatment agents.
Not that I can imagine why would anybody wish to eat those, though.
