In all the years of being in this business, Ive never heard of a guestlist on a door that is not authorized by management. Door operations are either under management supervision (i.e. staff) or management authorization (i.e. direct permission with the lead promoter). Ive never heard, nor can imagine, someone "parking" themselves on the door and waving their hands and saying "hi, I have a guestlist". I will tell you, though, what you might be referring to is a subpromotion situation, where a lead promoter has a authorized list with the venue and brings in 10 subpromoters. That night, they pass in their lead list with 10 sub lists on it. Its the job of the lead and the door op to say "here's my list, and my 10 subs lists are called X, Y, Z". The sad thing about LA nightlife currently, as I was discussing with a new team partner the other night, is that back around 2003-ish, you had about 3-4 promotion teams (lalate included) that could fill a venue in one night solo or in partnership with another team. Their lists are that big. Today, the new teams entering the industry since 2004 really dont pull in the size of lists that promoters use to do. They are growing. But they really havent grown as fast as pre-myspace promoters use to. It may be a factor of how lists were generated pre-myspace, maybe not.
