It's been a long time since I've been on the dating scene.
But I'd say that my red flags would include:
- bragging about sexual exploits
- talking incessantly about ex's
- getting too drunk (drinking responsibly on a first date is ok, getting falling-down-drunk is not)
- smoking (social smoking is ok, but regular daily smoking is not)
- admitting to current, regular use of illegal drugs (get off the drugs first, then we'll talk)
- strong fundamentalist religious views (e.g. a woman's place is in the home, watch your skirt - you're showing too much ankle, etc.)
- dresses in a very sloppy manner (e.g. torn or stained clothes) or in a manner inappropriate to the venue (e.g. jeans or sneakers at a very nice restaurant)
Yellow flags:
- late without a good reason (this is the
first date - even if you're so chronically late that you'd be late to your own funeral, you should at least
try to pick me up / meet me on time!)
- not tipping, or lowballing the tip, unless the service was actually bad (I used to date a guy who would never tip waitstaff or cab drivers...

)
- can't hold a conversation / gives one-word answers to open-ended questions
- dictates where we are going on the date. Asking me what type of food I like, asking me if I have a restaurant to suggest, suggesting a type of cuisine or a specific restaurant and asking me if I'd like that - all are good. But "I know this great place where they serve only liver and brussels sprouts, and that's where we're going!" is not ok.
Okay, so I'm picky.
