wait in line vs wait on line

I went to the station to try to meet you from the train, but I was late because I had to wait in line for 20 minutes just to get in.

The sign says "Wait in line."

I don't know why, but we all had to wait in line for a stupid $1 donut.

I hate it when I wait in line, especially if the person in front of me has smelly hair!

If the customers wait in line for more than 10 minutes, they will think our product is more valuable.

When winter comes, it is far worse to wait in line outside. In the summertime, I don't mind it so much (apart from the mosquitoes)

While we wait in line, thieves and brigands skip ahead gleefully, little knowing that they were skipping to their deaths.

Why would I bother to wait in line for something I don't even like?

"You'll just have to wait in line like the rest of us."

The president of the company had to wait in line like everyone else, and she wasn't too happy about it.

Sir, would you please mind waiting in line for the tickets here? Thank you.
