Is it normal to be charged a bond in amateur musicals?

Not sure who to feel sorrier for, you or the company. I wonder if they got "stung" big time by people dropping out in the past? Or if it's simply become a custom and practice thing? Maybe they're broke and can't put the show on without it? In which case, just say so. Still, all a bit fishy to me. I guess you need to do a list of pros and cons in regard to your involvement and settle it from there but personally I'd steer clear. We all put our hands in our pockets when we do shows (except usually pro shows) but that's just a bit too much for my liking. I'll fund my own undergarments/tights/make up/certain bits of costume/membership very happily for most shows but I think I'd draw the line at this bond. It's purpose seems a bit "off" and certainly implys a lack of trust, not a good basis to form a company with. "Papa, where is Mama? They tell me she has gone away, where is she?"
