We had to wait in line for an hour when we got there.
Do you know why the wait was so long?
Because they were giving away free bourbon in there.
That's a long line, but it's good that you were able to wait patiently. Have patience is an important characteristic to have, even in situations like having to wait in line for a long time.
Man, I want to make a complaint about the bar being overcrowded. Can we do that?
It's good that you waited patiently, but I definitely get that it was crowded once you got inside, too. I think you should just carry about the sense of patience to the crowd inside too as it's understandable as to why so many people were there.
