I think I work with a bunch of princesses!
Well I think it is pretty obvious WHY those girls you work with are still single

I think Fridays or Applebees is fine for a first date. -Full disclosure: I am a woman and I totally take the male coworkers' side on this

.
I agree. These women sound very superficial and full of themselves. I doubt very much they have the class to attract a man who can afford to drop $200 in a single date.
A 5 star restaurant is some place you take someone for a special occasion. I would actually be very suspicious as to
why a man would need to impress me so much, if doesn't have money like Donald Trump to drop on a dinner like that every night. I'm more interested in finding out who the man
really is. Not what he's like when he's on his best behavior trying to impress me, being someone phony.
Oh, and unlike someone who said they wouldn't go someplace where they can drink. I would. I want to find out first off if the guy is an alcoholic or not or has a potential drinking problem. An alcoholic would naturally order a bunch of drinks without thinking,

or would feel very unnatural NOT drinking,

if he was not drinking (because I don't,) to impress me.
Maya Angelou, Oprah's trusted, elder advisor & mentor says: "People
always show you who they are in the first 20 minutes of meeting them.
Our problem is, we don't want to believe it."
Police profilers and counselors know this to be true. People always leak who they are. Some people are itching to tell you.
I think those girls in your office said loud & clear who they are. For me, a potential alcoholic would show himself, too. I know the signs to look for, even the subtle ones.
