I am sorry that I forget who asked me this question....BUT....
Yes, sometimes I work in the box office when I am IN a show. We have two shifts..... 5 p.m. to 7 p.m. Ticket Sales/Phone
7 p.m. through intermission - ticket sales, refreshments, Phone
So if I am in a show, I just do the first shift a couple of times, but when I direct a show, I usually try to be the third person in the box office during the intermission.
