[Callers] End Effect Rules for callers

[Jim Hemphill]

Great idea for a workshop for dancers, but I'm curious what the callers
approach to these types of dances are.  Many of the dance weekend caliber
callers seem to take a very cavalier approach, often saying something like
"This dance has some unusual end effects, be ready and good luck" or
nothing at all.  Sometimes this works out ok, sometimes not.
