I remember being in an O'Neills bar a while back and reading their food menu. They had these fantastic sounding sandiwches along the lines of
"3 succulent Irish pork sausages and carmelised red onion with all the trimmings* in thick-cut brown bread"
This sounds utterly fantastic. Especially as it has ALL the trimmings, which make it sound like a real feast.
Underneath was this clause
*trimmings include tomatoes, lettuce and mayonaise".
which made the above description the best piece of over-selling ever.
