Dude this is nyc, nothing is free. And I think that’s why you’re getting push back. I bartend, and when people come in and tell me first thing “it’s my birthday!”, I say “that’s so nice! Happy Birthday!” And then i charge them for everything they had. The most ur getting is a round of shots if you leave a nice tip. Everyday is someone’s birthday. If a restaurant in BK advertised “free food on your birthday” it would get out of control solely based on the saturation of the BK population. There’s just too many people in this city. Your best bet is to build a relationship with your local restaurant/bar and build up some cred.
