Uhhh, free shots from the bars. Free desert at many restaurants. Free play at many casinos. Maybe a few birthday spankings at a good strip club. The possibilities are endless!
And yeah, a free shot from the bartender. You can also get free shots from other customers (a lot more if you're a girl), but most of those shots will be "blowjobs."
if you have a wife or a gf demand a bday bj from them and end you sentence with "or else". also if you were a kid and lived near a kroger you could get a free cookie from the cookie club ( thats if they still do that).
