Does buying someone a drink show level of interest in you?

Say you see someone new at the bar and want to get to know them do talk to them first and let them buy their own drink until you have exchanged names etc or do you go for it straight away? Or is it not a level on interest thing? Or how hot you find them?
Buy drink straight away is showing level of interest and how hot you find them
It doesn’t and nothing to do with how hot you find them
