Is it normal coworker asked me to have coffee outside work?
I recently switched jobs and at this new company is a hot female coworker with short brunette hair. She has been trying to get my attention and flirt with me for the past one week. She always attempts to make eye contact with me and smile. One time I was sitting down and she came up behind me and gave me a good shoulder rub. Another time she asked for my help in fixing the stapler but when I got to her she said it fixed itself because I was too slow. This other time she sprayed some hand sanitizer on my left hand when I wasn't looking. Today she discreetly asked me to have coffee outside work. I just don't know what to think because she is very attractive and no woman has ever acted like this around me, it makes me believe it could all be a prank or some kind of ridiculous bet. I have no way of knowing if she is genuine or just messing with me. She is acting immature even though she is older than me (I'm 24, a straight guy, and she's 26).
