“Do not just star, buy me a drink”

Today, I went to a pub with my landlady and her family.
Her family means her mother and her blind friend.
Her mother became great grand mother this year , but she still drive and dance at the pub. Actually her dance is cool.
Today I wore a T-shirt I got from my landlady. The T-shirt with the sentence “Do not just star, buy me a drink”. Cool joke isn't it?!
By the say, I did not get any free drink there although I did not expected.
