Having visited both locations over the years, I would generally agree that you do get a bit of extra mileage at ST. However, the right girl at BG can easily match anything at ST--but that is a gamble. You don't really know how she is until you pay your dues after walking through the door.

I have had some great sessions at BG and at other times, real duds that were better suited to working behind the counter at Starbucks. The turnover rate at BG is also a bit higher than ST. It bums me out every time I find a real "gem" at BG, she leaves in a few months.
