Usually the second question I ask when approached to do any league outside the regular season whether it is fall, spring or summer is: "full dress, or can we wear shorts." If we can wear shorts, I then ask if they require black sox and/or shoes. If not, I wear black shorts with white sox and shoes. The reason is that I can find white sox with extremely thick, cushioney soles, but I haven't been able to find black ones that way.
BTW - the first question isn't how much we get paid. It's whether or not we get free pop.
