what do you say to people who just come to sing and not buying anything

[swany]

Most bars I know will ask if they are drinking or eating if not they generally ask them to order something or leave, as it is not a rest stop. I do have some regulars that drink coffee, tea or water but tip for the service. That particular place seats 200 and is hardly ever at capacity. When I get singers that are in that group I generally play a few dj songs in between singers and they tend to start buying more to drink.
