Am I being paranoid?

I went to a coffee shop today to get an iced coffee. The woman taking my order touched her crusty lip before taking my order and then made my drink but she touched the rim of the cup. She put a lid on and I took a wrapped straw and drank from that. The liquid didn t seem to go to the top of the cup. I used a clean straw. Is it possible to get herpes (if she had it) from her touching her lip then touching the rim of the cup after taking my order? Am I being paranoid?
