If I brush his hand and make eye contact while giving him change will he think I'm dtf?

There's a cute, new cashier at a cornershop I frequent. He is quiet but I can tell we like each other.

It's always busy and there is always other staff around. They are all guys and have all shown signs of attraction but I don't like any of them. Except the new guy šŸ˜.

I want to get his attention to let him know I'm interested.

I figured I would make sure to really rub his hand when I give him money or take the change. I am afraid he will take it as a sexual invitation.

I want to subtly let him know I'm interested. He had been staring a bit and gave me some free snacks but is all quiet now.

If I do that will he think I'm DTF? Is that slutty? I don't want to give the wrong impression.

I won't be doing that. He is quite shy. I will just be really friendly and build rapport. No rush.
