All our gigs are for money (charity ones excepted, but they've got to be proper charity, not someone playing at being a promoter). One pub I used to play at would also let you have free soft drinks all night, another couple would give you the first drink, and another one or two did free drink all night. The fact that I can't remember which pub it was that gave us free drink all night does show the hazard of having it (the two pubs I do remember were in Munich, and we're still waiting to get another gig there...).
