Today I was standing in line waiting to get coffee when @ one point the girl behind me grabs my upper arm/side shoulder as she moves to the next cashier and asks me "whether or not I was being served". This particular spot had two right beside each other so sometimes you can move to the other side of the person in front of you if they are being served. Although its sometimes hard to know if they've already ordered since it goes quickly. So anyway the question she asked me seemed legit and I wouldn't usually think twice about it, but the fact that she grabbed onto, and kind of applied pressure to my arm as she walked by struck me as odd. It actually kind of suprised me when it happened. So my question is whether or not this can be considered her being attracted to me, or are some girls okay with touching strangers (guys) like this.
