I probably would not realise it at all when someone is flirting with me, I dont easily pick up signals like that. If it would happen, I would dislike it. I am a rather introvert and serious person unless I know someone well. So when someone approaches me she better uses regular conversation rather than flirty behaviour, if she is flirty I would probably assume she is just after some fun and not after a serious friendship or relationship. Maybe a wrong assumption, but that is because I dont like flirting in general and thus will easier open up to a woman if she approaches me in a more serious way, starting a normal conversation.
