Is it normal to have a crush on a fastfood worker
I have a massive crush on a fastfood worker. For this reason I go there every week on Saturday. Lately I believe she "recognised" me so I decided to only go every 2 weeks to avoid looking like I have no life which is indeed the case. Every now and then I'd say bye to her when I leave or talk very shortly. This way I know she is Assyrian. I'm way too shy to continue the conversation or generate attraction as pua's would say, so after I talk briefly I eject politely.
Also I'm much older than her. I'm in my thirties and she must be about 22.
Is this normal and what can I do to approach her properly?
