Uch I'm not a vegetarian or some health freak but the amount of meat they put in some dishes... It just completely overwhelms the taste.
And at the risk of sounding like an eco warrior terrorist I think meat is too cheap if you can put an entire sausage on a €7 pizza.
There is an environmental cost that isn't priced in- and a health cost too.
"Pile" typically refers to sliced deli meat, i.e. "pastrami piled high". You may confuse the customer into thinking that there's also deli meat on the burger when there isn't.
More likely their product teams would have done better with a name that didn't refer to the portion size.
