Went with my mom and her friend from SF to DAI HO for dan dan noodles and stewed duck wings. First, he made us share a large table with another party, even though a small table was open. After that party left, he seated another party of 2 with us.
They made the mistake of only ordering a soup first. When they tried add an order of noodles later on, he refused. They thought he was joking (first timers). My mom told him he should be understanding, because it was their first time. He said if it's their first time, then they need to learn.
The thing is, even after witnessing this boorish behavior, my mom's friend still wants to go back tomorrow to eat there again. Go figure.
