She's Got Betty Grable Eyes

This is somewhat of a rant I suppose. I'm not the prettiest girl on the block, so I have no idea why I've been getting hit on so much lately. All while at work. Just let me do my job people! Here is a sampling of what I've heard in the past 3 days:
-You look just like Betty Grable, the pin-up girl from the 1940s
-You have the most amazing eyes I've ever seen
-I really like your aura, are you single?
-You have eyes like those models on TV
-You know, Valentine's Day is coming up, would you be my Valentine?
And the zinger is...
-(after asking a customer what he won on a scratch card I gave him) Look, I won free sex with the girl that gave this card to me!

Sigh... I guess I've gotten too pretty for my own good! Ha, if only that were true. But the guy who asked if I was single and the Valentine's guy were totally serious when they asked me.
Do guys really not look at a girl my age's hand before asking these questions?
