When I had my pub I had a rule on barstaff: Fit, attractive girls who are tough enough to deal with a bit of banter. I wouldn't stand for any harassment, but they had to be able to deal with the odd clumsy chat up attempt or 'compliment'.  My customers were mostly working men (builders, sparkies, roofers etc) who come in after a hard day for a pint or two, and they didn't want to see my ugly ass behind the bar and certainly not some fat munter. My two best barmaids used to make more than me, in tips (in the UK too) and they definitely brought the punters in.
