One of the choices I personally made was: Locale's Customer Base
Personally, I wouldn't want to bring my wife to meet her man in a bar full of the proverbial "teeny bopper" crowd ~ the age 21 - 24 college students, nor would I want to bring her to the likes of a Lion's Club type of lounge filled with old men.
Preferably, I would want a locale that is aged correctly, within income standards and not kiddish, oldish, too uppity, or serves only Milwaukee's Best.
I would want a place that the ladies dress classy, the men dress comfortable... an overall mid-range age and income matches the lower-toned music and dance environment: A place that it's music is loud enough to dance to, but not too overpowering as to need to rage to. A locale that allows a man and woman the ability to talk, without yelling ~ but also the "excuse" to get closer to hear each other.
Just my thoughts on "Customer Base" choice.
