Any helpful advice or comments on this interaction?

Cashier (F) told me (M) that I look like a “super model” tonight. Not sure if I should chalk it up to politeness since she’s a cashier or if she was interested in me? After her comment I said “thank you” and we were both silent until she said “have a good night”. I was expecting her to ask for my number since she was confident enough to say something like that but no go, so my curiosity has peaked.
Thank you in advance for any help or comments, sorry if I messed up on anything brand new to reddit.
