If guests are not active enough, you just come up to their table, take them by the hand, lead them on, put them on the tray and do you thing. I never limit myself in time when putting guests inside bubble. While the guests want it, I'll work. The exception may be a situation where there are another 10 artists are waiting for their turn to present their shows.
If the show-ballet is waiting for their turn, it will be disrespectful to them. And if I'm the only artist then why not. There are props, my assistant gets paid, and I like my job. I just know that the guests will be satisfied, and I will be very pleased too.
