Yes. Talk to the Manager. They want more business, and want to incentivize you to bring people in to their place of business.

The bartenders? You are just more work. They don't make more money if you come in, and then you take your patrons away to another bar. They have little motivation to do more than the minimum for you. So you need to have an official arrangement with the manager, and the manager needs to tell the bartenders how to meet the arrangement you have with the manager.

I used to be a Ghost Tour Guide in Pike Place Market in Seattle, and also did the affiliated Lust Tour. (Here's some proof. And More Proof under a different name, and me again.) I walked people around the market after closing hours, and told them ghost stories and the gory history of our city. (Like Dr Linda Hazzard, the "Starvation Doctor", active hauntings that still happen almost weekly in a bar called Kells, that is where the mortuary used to be. The brothel that used to operate in the Market, and what would happen when the navy fleets of thousands of men came to a brothel that employed 30 women... The ghost of Chief Sealth's daughter, "Princess Angeline", which is still seen in the Market sometimes today... etc.)

The Lust Tour was a seriously dirty/sexy/gross history of Seattle's 1st Ave, which used to have the highest density of porn shops anywhere in the world. Fun tour...
