Personally I think many of you are making too much of this. The poster’s PARENTS are apparently not concerned, so why are you? People have to learn how to deal with all types of situations, INCLUDING deflecting unwanted attention (and I am not sure this even qualifies, as it sounds like these employees are just very friendly, and things are being read into).
Yoyo, if you are really that bothered, STAY OUT OF THE STORE, though I think you are over-reacting. Store owners encourage their employees to be friendly to customers, and if it bothers you that they are, to the extent that you feel it is too much, then either refrain from going in there, or keep the conversation light, short, and away from personal subjects. Hello, goodbye. If they mention you working in the store, say “not interested, but thanks,” and then walk away.
Part of growing up, is learning how to maturely deal with this type of occurrence. It will happen in the workplace, in stores, sometimes on the street. When we grow up, we need to not get thrown by this, and we learn to tell the difference between TRUE harrassment and just plain over-friendliness. And btw, just because someone asks for your number (which they did not do), does not obligate you to give out your personal information. So it is highly unlikely “they could do whatever they want.”
