If it's clearly unfit to eat, why does First Floor serve it to me?

This place must be a great place to drink, however..

Everthing was just acceptable. We ordered some pasta, mini burgers and some spring rolls. Everything was acceptable I guess for a pub. We had to scream for the surly waitresses and interrupt them from their game of cards every time we needed anything. Other times they took things off our table that weren't even finished. What, are they that short of dishes?

What really irked me was that the spring rolls we ordered came out looked ok but there were a couple at the bottom of the stack that were literally burnt out shells, black and deliberately hidden on the bottom between garnish. When I asked the waitress, and I use that term lightly, she said you've already eaten most of them and walked off. A second waitress said sometimes they burn, basically mei banfa. So if it comes out of the fryer looking like dog crap, why do you serve it in the first place?

Over spiced burgers, couldn't taste the meat, wondered what else they are hiding.
