OP: If it's just dating him, sure why not?
But if you're looking to have a long term BF situation, I reckon it will eventually fizzle out between the two of you. Bartender schedules are long, late night. People like urself that will most likey have a "day job" will not see ur bf often because when u come home at night, bartender boy is gearing up for a busy night at the local watering hole. You'll be going to bed alone, prob wondering what he's doing, when he'll be home....just like a lonely housewife.
but for dating? yeah man go for it.
oh and scruffy, i know what u mean, but their schedules are just too much...too fucking late all the time. And on a more shallow note: after years of bartending, they tend to look old and haggard before their time, imo. Sunken eyes, lack of sleep, lack of sunlight really (work all night sleep all day), just end up looking like hell after a while.
