A stranger told me he’s jealous about me talking to other guys on a scale of 1-10 how creepy?

Basically I work at a store he comes in regularly normally he just stares (which other guys do so I didn’t think much of it) then today he told me I don’t like how you talk to other men you are making me jealous 😬 I was literally only saying work things like ‘did you find everything ok?’ and ‘have a nice day’.

He said it seriously with an angry face not like he was joking or flirting

I did tell the people I work with they were kinda like surprised but found it funny
