Liza meant - they should be more "presentable." Maybe dress better, take some extra care in their hygiene/health(gym)/homes, and adjust their attitude.
There are several car dealerships on the same street. I'm sure you'd pick a place that looks nice and presentable. You're certainly not going to a shoddy looking place with some overgrown weed unless you're looking for some cheap-ass car
And if there are 2 clean car dealerships that you like... how do you decide which one to go with? You'd pick the one that has a salesperson with good attitude. You don't want one who is very over-bearing on you or very pushy/aggressive/hyper. I know some people have infantile interests. For ie - I'm sure most of you have seen 30-years Old Virgin movie. Having all these toys and game stuffs is not going to score you a point unless you found a really cute geek who digs it (but what are the chance of that?
).
meanwhile..... CHEER! and work on yourself first if you want a girl to take a second look on you!
