Be kind, respectful, and positive
"Bouncers occupy a weird space -- they have all this power in the moment, but overall, many of them belong to a lower rung in social hierarchy than the people trying to get in the bar or club. You can definitely use this to your advantage -- by using all the tips I previously gave you, and by just treating them with simple kindness and unforced respect.
"When you approach a situation with an overall sense of positivity and good nature, you automatically trigger the neurons in other people's brains to make them feel a sense of well-being, too. Be happy to see the bouncer. Smile. Don't be a jerk. This is the most basic advice I can give anyone approaching a negotiation. It's so simple, but so often overlooked."
The decision to let you in or not, is not a rational decision. It's an emotional decision.
"At the end of the day, the best way may be putting a smile on their face," Voss said. "I remember once, a panhandler stopped me in the street, and asked me, with a straight face, if I'd like to 'donate to the United Negro Pizza Fund.' This stopped me in my tracks, and I gave him some dollars. After that, I'd go out of my way to pass by his spot, and give him money every time I was in town.
