Perhaps it depends on how you describe what you do, to potential bookers.

Are you able to say what the guy said to the landlord, i.e. how he 'explained what he does'? It would be interesting to know how much detail he went into, etc. Presumably you were able to listen and maybe get some tips on how to go about it.

(I don't book our gigs myself, so this is something I don't know much about)
