I used to go to Lee's in Irvine, CA all the time as an undergrad and had to make a lil' nostalgic trip on through while in China town. The service at this location was horrible.
I waited in line (only one in line) for five minutes before I kindly asked if I was in the correct line. The cashier told me yes, and continued what she was doing. When she was done she said "... you can order..." and wasn't even looking at me or standing at the cash register. I ordered and was charged more than the menu price so I questioned why, she told me because I ordered a large. I pointed out the large was less than what I was charged and she shuttered "... oh... um, they changed the prices" which would have been fine had that had been her reasoning in the first place.
It wasn't even busy. And that is the ONLY way I forgive bad service... Guess I'll only go to Lee's in CA
