how do you say the N word?

ok. I'm writing this because of something that happened to me today, that reminded me that I've been on this situation on many occasions before, and never quite knew what to do.
confused?
I'll explain.
today, as usual after my instructions I went to eat launch on the central bus station of Jerusalem, which is like a lil mall. as usual (ooh I like that phrase), I was sitting alone since the other instructors were, well, still instructing. anyways, since it was crowded and there weren't any free tables anywhere, one guy came near my table, and asked if he could sit there. I said yes, elementary. well, he sat, and out of the blue he suddenly told me "bon apetit". I do not know that man. hy would he tell me "bon apetit"? my suspects began to raise. "oh ho" thought lil Neta "I'm being hit on". why the "oh ho", you ask? you'll quickly understand. as it developed, I was right. after a while of quiet sitting in front of me the guy starting talking to me. asked me where I was from in the country, where do I serve in the army, how long does a working day of mine lasts, long story short- the all bla bla bla and bli bli bli of hitting with girls. I wasn't interested to begin with. yet I cooperated. why, you ask? because I'm an idiot, that's why. this sin't the first time I give a positive feedback to guys who hit on me when I'm not the least interested in them. no, it's not because I'm an evil meano, that wants to play with the poor guys' hearts, make them feel they have a chance, and them brutally kick them to the curve. for a matter of fact, it's exactly the opposite. just because I DON'T wanna hurt them, I keep on playing positive. and, yes, I'm well aware that this is hurting them even more than just telling them from the start, because it's like pulling them with illiusions, making them believe in something that you already know is false. that's why I'm asking your help, sillies! lol
the guy eventually asked me when can we continue our talk, I told him that maaaaaaaaaybe we'll meet sometime on the station, he didn't quite get my hint, and asked me for my phone number. ooh, here's the tughy part. remember the topic of this thread? this is where the unpronouncable N word (that if you hadn't guessed it yet, it's No) comes to play. a normal sane girl, when not interested, will somehow manage to politely tell him that she's sorry, but she's not interetsed, and will charmingly fade away in her good fairy's dust. but remember who you're talking to. I'm not normal, and apparently not very sane either. you see, I started twisting in my own lies, telling him my home number was disconected (lie), my cell is broke (lie) and my army number is not forbidden to be called to (why, I think that would be a lie too! ). so, yea, eventually I made the poor guy write his phone number and give it to me. "will you call?" "I...'ll try.. you know, I told you I'm very busy and vearly have time for myself lately.." says one frightened lil Neta. did you think that's here is where the story ends? well, let me turn on the buzzer for you- EHHHHHH! wrong answer. the guy works as a security guard on the station. the same station I come to on every day of my stupid army life. the same station which is now sadly a second home to me. a security guard. which means I can't enter the station without passing through him at the enterance. now, that. my friends, is a hard one. "well, nevermind" he says "I'll see you here anyways, I work here and you said you come here every day". stupid stupid stupid!! why did I tell him that?!
ok, see? this is the typical process Neta goes through whenever someone hits on her, cuz, what can I do? most of my beaux if not all of them, I just don't like. so here comes the question, especially directed for the girls here, but if you guys over there feel like you can help, I'll be glad to hear your thoughts- what do I do/say whenever I'm being hit on by a guy whom I don't like? how would I reject him without hurting him, and without being a total b*tch? and basically, how, oh, how so you say NO??



thanks.
